Eggs pack more protein per bite than almost any other food source in nature, which is exactly why so many animals that eat eggs will go out of their way to find them. A fertilized egg is a complete, ready-to-eat meal wrapped in a convenient shell, and predators from tiny ants to full-grown coyotes have figured that out. Whether the target is a robin’s nest in the backyard or a clutch of chicken eggs in a coop, the list of creatures willing to raid it is longer than most people expect.
Understanding who the culprit is usually comes down to reading the clues left behind. According to Discover Wildlife, birds’ eggs are a nutritious source of food, so it’s hardly surprising that lots of animals eat them, and the damage pattern left on the shell often points straight to the species responsible. The table below breaks down some of the most common signs.
| Animal | Typical Sign Left Behind |
|---|---|
| Raccoons | Crushed shells, paw prints, scattered nesting material |
| Rats | Small hole with chip marks, contents licked clean |
| Snakes and corvids | Single puncture hole, shell often left in place or nearby |
| Skunks and opossums | Messy, torn shells with obvious struggle marks |
Missing or damaged eggs may be caused by skunks, snakes, rats, opossums, raccoons, coyotes, foxes, blue jays, and crows, according to Ohio State University’s Ohioline extension service. That single list already covers most of backyard egg predation, but the full picture is broader once wild nests, turtle eggs, and even insect activity get factored in.
1. Raccoons
Raccoons (Procyon lotor) top most predator lists for good reason. Raccoons have a vast diet, consisting of just about anything they can get their little paws on, including bird eggs, and they will also snatch turtle eggs if they come across them. Their dexterous front paws let them pry open latches and reach into tight nesting boxes that would stop many other omnivorous animals cold.
In a backyard coop setting, raccoons rarely stop at eggs once they find an easy way in. Raccoons are notorious for digging under barriers and climbing over fences to get into the chicken coop, and they can be ruthless, even killing and eating adult birds if they get the opportunity. Securing latches with two-step locks and burying wire mesh around the coop perimeter are the most reliable deterrents.
Pro Tip: Raccoons are strong enough to open simple slide bolts and hook latches. Use a carabiner clip or a combination lock on nesting boxes to keep them out.
2. Cats
Both feral and free-roaming domestic cats (Felis catus) will eat eggs when they find them, though it’s a secondary food source rather than a primary target. Their hunting instinct is tuned toward moving prey, so a cat is far more likely to raid a nest while stalking the parent bird or a nearby small mammal like a rabbit than to specifically search for eggs. Once a nest is discovered during that hunt, however, the eggs rarely survive the encounter.
Ground-nesting birds are the most vulnerable to cat predation because the eggs sit at exactly the height a cat naturally patrols. This is one reason conservationists in many countries encourage keeping outdoor cats contained during nesting season, particularly in areas with sensitive shorebird or songbird populations.
3. Dogs
Dogs (Canis lupus familiaris) are opportunistic omnivores, and a curious dog left unsupervised near a chicken coop or a low nest will often investigate eggs simply because they smell interesting. Unlike raccoons or snakes, dogs don’t typically hunt for eggs as a food strategy; the behavior is closer to general scavenging than deliberate predation.
That said, some breeds with strong prey drives will actively dig up ground nests belonging to turtles or burrowing birds. Owners who keep backyard flocks generally find that a well-trained dog can actually deter other egg predators like raccoons and foxes simply by patrolling the yard, turning a potential threat into a useful guardian.
4. Snakes
Snakes are some of the most specialized animals that eat eggs on this list. Research on king snakes (Lampropeltis getula) published in the Journal of Field Ornithology found that adult specimens could only ingest modestly sized eggs relative to the dimensions of their feeding apparatus, whereas juveniles could not ingest eggs at all, showing just how tightly body size limits which eggs a snake can swallow. Even so, this pattern is not without exception given that several snakes consume bulky chicken, duck, and goose eggs.
The genus Dasypeltis, commonly called egg-eating snakes, takes this specialization to an extreme. Their diet has resulted in an evolutionary adaptation that removed their teeth and substantially increased the capacity of their necks, allowing them to swallow whole eggs, crush them against bony projections in the throat, and then squeeze out the liquid contents before regurgitating the shell. In a backyard setting, more generalist species matter more: while snakes don’t typically go after adult chickens, they will often prey on chicks and eggs, using their climbing ability to slither into tight spaces and hide in tall grass near the coop. Anyone dealing with repeated predators of snakes in the yard may find that controlling rodent populations indirectly reduces snake activity too, since rodents are what draw many snakes in.
5. Crows and Other Corvids (Magpies, Jackdaws, Rooks, Ravens, and Jays)
Corvids are widely considered the most persistent avian egg thieves. Crows and other corvids, including magpies, jackdaws, rooks, ravens and jays, are probably the most common predators of bird nests, actively searching hedgerows and scanning the ground from trees for nesting birds. Their technique is precise: they make a small puncture in the side or end of the egg, then insert their upper bill into the hole to lift the egg and drain the contents, often carrying it off to a favored eating spot.
Ravens (Corvus corax) take an especially strategic approach. Ravens patrol territories looking for nests, then remember the locations to return once the adult birds are away, and are especially likely to target large eggs like those of hawks, eagles and owls, carrying the heavy eggs away and dropping them from a height to crack them open. Magpies (Pica pica) are no less methodical; once a clever magpie locates a nest, it will keep coming back time after time to steal more eggs, and some studies show a single magpie can destroy nearly 50 nests over just a few months. This intelligence extends across the whole family, since this egg-stealing behavior is particularly common among corvids, which are renowned for their problem-solving skills and bold foraging tactics.
- Magpies often work in pairs, with one distracting the parent bird while the other steals the egg
- Jackdaws and rooks tend to target unattended farmland and hedgerow nests
- Jays frequently raid smaller songbird nests during daylight hours
- Ravens specialize in larger eggs and will drop them to break the shell
6. Possums
Opossums (Didelphis virginiana) are opportunists rather than egg specialists. Eggs are not the first choice of food for opossums, but that doesn’t mean they won’t grab one if nothing else is available, and they have been known to raid the nests of various birds, eating both the eggs and the smaller chicks. In a coop setting, they’re also fairly easy to spot in the act, since opossums are not nearly as aggressive as raccoons, are nocturnal predators, and are creatures of opportunity looking for an easy meal.
Interestingly, opossums are among the animals that sleep a lot, often resting up to 18 hours a day, which is part of why their nighttime raids can go unnoticed for so long. They’re also one of several animals starting with the letter O that show up regularly on backyard predator lists.
7. Rats
Few animals are as consistently blamed for missing eggs as rats. Rats will eat just about anything, including the eggs of other animals, and they are a common problem in chicken coops, stealing eggs from hens and sometimes hurting the chickens in the process. Brown rats (Rattus norvegicus) are the most frequent offenders in urban and suburban settings.
Their feeding style leaves a distinctive signature. Rats prefer the large, cryptic eggs of colonial nesting birds and consume the eggs in the nest, making a hole in the side or end of the egg with characteristic chip marks, then licking out the contents. According to a detailed predator-identification guide from One Acre Farm, rats chew up eggs in the coop or carry them away, eating entire eggs and young chicks and leaving no remains. Anyone tracking down a persistent rat predator problem in the coop should start by sealing feed containers, since rats are drawn in by feed long before they discover the eggs.
8. Coyotes
Coyotes (Canis latrans) are generalist hunters that will happily eat eggs when the opportunity arises, though they’re better known for going after adult poultry and small mammals. Their omnivorous diet means eggs found on the ground, in low nests, or in an unsecured coop are simply added to whatever else is available that night, alongside rabbits and other small prey.
Ohioline’s poultry predator research lists coyotes among the standard suspects for missing or damaged eggs on rural properties. Because coyotes typically hunt at night and range over large territories, repeated egg losses combined with tracks or scat near the coop are usually the clearest signs that a coyote, rather than a smaller predator, is responsible.
9. Skunks
Striped skunks (Mephitis mephitis) are far less picky about their egg sources than most people assume. Skunks are not picky about whose eggs they steal, and if given the opportunity, they will eat the eggs of chickens, turtles, and nesting birds. Their reputation for spraying when threatened doesn’t stop them from being persistent, methodical egg thieves.
Skunks are also skilled diggers. According to The Hip Chick, skunks will burrow under the fence and have a go at your hens’ eggs or simply find an unprotected nest to devour. Because they tend to leave a visibly messy scene, skunks and opossums are messy eaters that will leave behind obvious signs of struggle, which makes them one of the easier predators to identify after the fact.
10. Foxes
Red foxes (Vulpes vulpes) are notorious for raiding both nests and coops, and eggs are a regular part of their diet whenever they’re available. A fox will often catch mallards, pheasants and partridges on their nests, and eggs left unattended nearby rarely survive a visit. Backyard flock owners report similar behavior: foxes will also eat eggs, and if a fox has been after your eggs, you’ll likely find empty, broken shells in the chicken coop the next day.
Foxes are efficient rather than messy. Unlike skunks or opossums, they tend to leave a cleaner scene, taking whole eggs away when possible rather than eating on-site. Their skill at slipping through small gaps makes them a serious threat to any predator of squirrels and other small yard animals, with eggs simply being one more item on an already varied menu.
11. Turtles
Turtles occupy an unusual spot on this list because some species eat eggs that aren’t even their own kind’s. Snapping turtles (Chelydra serpentina) and several other freshwater species are known to raid the nests of other reptiles and ground-nesting birds when the opportunity presents itself, particularly in wetland habitats where nests sit close to the water’s edge.
Turtle eggs themselves are also a frequent target for other predators on this list. As noted earlier, raccoons will readily snatch turtle eggs when they find a nest, and skunks are known to do the same. This makes turtles both predator and prey in the egg-eating equation, a dynamic worth exploring further alongside other animals that start with the letter T.
12. Squirrels
Squirrels have a reputation for stealing seeds and nuts, but eggs are very much on the menu too. Chicken eggs are part of the diet of many animals, the most common being rats, squirrels, snakes, raccoons, and crows, with squirrels known to break into coops especially during springtime when they need to stock up on food and egg production is at its highest.
Their feeding marks can be easy to confuse with rodent damage from rats. Squirrel signs are very similar to the chip marks left by rats, since both species gnaw a hole and lick out the contents rather than crushing the whole shell. Eastern gray squirrels (Sciurus carolinensis) are among the most commonly reported culprits in North American backyards, and their overall diet leans far more omnivorous than most people realize, echoing the flexible feeding style seen in many other plant-and-animal eaters.
13. Deer
Deer eating eggs surprises most people, since white-tailed deer (Odocoileus virginianus) are widely thought of as strict herbivores. In reality, deer are opportunistic and will occasionally consume eggs, nestlings, or other small protein sources, particularly during periods when calcium and protein are scarce in their usual plant-based diet.
Important Note: Documented cases of deer eating eggs are largely anecdotal rather than the subject of formal wildlife studies, so this behavior should be considered rare and opportunistic rather than typical. Deer remain overwhelmingly herbivorous, and egg consumption is far less common for them than for the other animals that eat other animals covered in this list.
14. Ants
Insects round out the list of animals that eat eggs, and ants are the most significant contributors. Fire ants (Solenopsis invicta) are especially aggressive around ground-level nests. In the southern United States, imported fire ants can overwhelm ground nests, consuming both eggs and hatchlings, making them a serious threat to ground-nesting birds and reptiles in warmer climates.
Ants aren’t alone among small invertebrates in this habit. A wide variety of insects like to feast on bird eggs, including ants, beetles, and wasps, taking advantage of any crack or thin spot in the shell to reach the contents inside. For anyone curious about how far this kind of opportunistic feeding extends across the insect world, the broader list of animals that start with the letter A covers several more examples.
From the methodical precision of egg-eating snakes to the brute persistence of raccoons and the surprising opportunism of deer, the animals that eat eggs span nearly every corner of the animal kingdom. Most of these encounters come down to simple math: an egg is a high-value, low-effort meal, and few predators pass that up when the chance appears. Securing nesting boxes, trimming grass near coops, and keeping feed sealed away remain the most effective ways to keep this long list of opportunists from finding an easy score.
