What should I check if my hens are pecking eggs in the nest box?

Overview
If your hens are pecking eggs in the nest box, start by checking the nest box setup, how often eggs are being collected, and whether the flock has enough space, feed and distraction. Egg pecking often starts with a simple trigger, but there can be several possible causes, so it helps to look at the whole routine rather than one issue on its own.
Things To Check
1. Check how quickly eggs are being collected. Eggs left in the box for a long time are more likely to get pecked.
2. Look at the nest box bedding. It should be clean, dry and comfortable, with no broken eggshell or damp material left behind.
3. Check whether the boxes are dark, quiet and private enough. Hens can peck eggs more often if the nest area feels exposed or busy.
4. Make sure there are enough nest boxes for the number of hens. Overcrowding can lead to stress and repeat egg damage.
5. Check the hens' feed and water. Poor feed access, boredom or mineral imbalance can sometimes contribute to problem behaviours.
6. Look for signs of stress in the flock, such as feather pecking, bullying, changes in routine, or disturbance from predators, dogs or noisy surroundings.
7. Check for weak, thin or cracked eggshells. Eggs that break easily may encourage hens to start pecking the contents.
Common Causes
One of the most common causes is simply that an egg has already broken in the nest box. Once a hen tastes the contents, the behaviour can spread quickly to other eggs.
Another common cause is poor nest box management, such as dirty bedding, too few boxes, or eggs being left too long before collection. Stress, crowding and not enough enrichment can also play a part.
Less commonly, repeated soft or fragile eggshells may be involved, especially if the flock's diet, calcium intake or general condition isn't quite right.
What To Do
Remove cracked eggs and any soiled bedding as soon as you spot them. Collect eggs more often, especially during the day, so there is less chance for pecking to start.
Refresh the nest boxes with clean, dry bedding and make sure they're calm, private and easy for hens to use. If more than one hen is laying, check that there are enough boxes and that the weaker birds can use them without being pushed out.
Review the flock routine too. Good-quality feed, constant access to water, enough space and some form of enrichment can all help reduce boredom and frustration. If egg pecking starts after a change in the flock or housing, that change may be worth reviewing first.
If the problem keeps happening, keep a note of when eggs are pecked, which hens are using the boxes and whether the eggs are thin-shelled or already cracked. That pattern can help you narrow down the likely trigger.
