Why Do Chickens Eat Their Own Eggs? (And How to Stop It)
Edited by Jennifer Bryant · Poultry breeder, Animal Science graduate, and Poultry Nerds Podcast co-host.
Most egg eating starts by accident. An egg cracks, a curious hen takes a taste, and she discovers that eggs are delicious. Once she learns the trick, others may copy her.
If you've found sticky yolk in the nest box and a hen with a suspiciously shiny beak, you're not alone. Simple management changes can help, although an established habit can be hard to break.
Why It Starts
Thin shells. Weak shells break easily. Hens need plenty of calcium for strong shells.
Crowded nests. Too few nest boxes means hens pile in and step on eggs.
Bright nest boxes. Eggs that sit in the spotlight are easy to spot and peck.
Boredom. Chickens with nothing to do will find something to do.
Eggs left too long. The longer eggs sit, the more chances they have to break.
How to Stop It
Collect eggs often. Twice a day is great, especially in the morning. No eggs, no snack.
Offer oyster shell. Put crushed oyster shell in a separate dish next to the layer feed. Hens eat it as they need it.
Add enough nest boxes. One box for every four hens keeps traffic down.
Make nests dark and cozy. A curtain over the opening or a box in a shady corner helps.
Add soft bedding. A thick layer of straw or shavings cushions eggs as they drop.
Use fake eggs as an extra. Some keepers try ceramic eggs or golf balls in the nest. Focus first on preventing broken eggs and improving the nest setup.
Keep them busy. Hang a cabbage, offer a little scratch, or give them a dust-bathing spot. Keep treats limited so complete feed stays the main meal.
Find the Culprit
Watch the nest boxes in the morning. Look for yolk on beaks or faces. Once you know who it is, you can focus on keeping her nest quiet, well padded, and free of broken eggs.
Catch It Early
Egg eating is easier to prevent than to stop. The sooner you fix the cause, the less likely the whole flock picks it up.
