Overview
If eggs are disappearing from the nest box and there’s no shell left behind, egg eating is one of the most common reasons. It can also happen if an egg has been laid somewhere else, broken and fully cleaned up, or taken by another animal. A few simple checks can help you work out what’s most likely.
Things To Check
1. Check whether the eggs are missing after a certain time of day, especially after laying, when hens are left undisturbed, or when you’re not at home.
2. Look for any signs of broken egg contents on bedding, perches, walls or corners, even if there’s no shell left in the nest box.
3. Check whether the nest box is dark, quiet and comfortable, or whether hens may be avoiding it because it’s cramped, bright, wet or dirty.
4. Look at egg shells from other eggs for thin shells, cracks or weakness, as these can make eggs more likely to break and be eaten.
5. Check whether you’ve seen hens pecking at eggs, lingering in the nest box, or showing interest in spilled egg contents.
6. Make sure no rodents, crows, magpies, cats or other animals could be getting into the coop or run.
7. Review feed, water and space, because poor routine, stress or competition can sometimes be part of the picture.
Common Causes
Egg eating is often the main cause, especially if a hen has learned to peck a cracked egg and then keeps going back for more.
Soft or damaged shells can also lead to eggs breaking before you collect them, which may leave little or no shell behind if the contents are eaten or trampled into bedding.
Some hens lay outside the nest box, and those eggs can be missed entirely if they’re hidden, broken or taken apart quickly.
Less commonly, another animal may be taking the eggs, especially if you’re finding the nest box empty at times when eggs should still be there.
What To Do
Start by collecting eggs more often, especially at peak laying times, so there’s less chance of a broken egg being pecked at.
Keep nest boxes clean, dry and well filled with suitable bedding, and make sure there are enough boxes for the flock so hens aren’t crowding together.
If you suspect a hen is eating eggs, remove any broken eggs quickly and avoid leaving spilled yolk or white in the coop.
Check the flock’s routine, including feed, water, perch space and stress from changes in the group, because a settled environment can help reduce opportunistic pecking.
It can also help to collect eggs gently and regularly, then store them safely away from the coop so there’s less chance of hens getting access to them.
