Overview
If a hen only eats eggs from one nest box, it’s often because she’s found a reliable source of food there, or because something about that nest box is making the eggs too easy to break. The good news is that you can usually make a few practical changes to reduce the chance of it continuing.
It’s worth checking the nest box itself, the timing of egg collection, and whether other hens are contributing to broken eggs. There can be more than one cause, so a bit of observation helps.
Things To Check
1. Check whether eggs are being left in the nest box for long periods before you collect them.
2. Look at the nest box for cracked eggs, thin shells, broken bedding, or anything that might make eggs more likely to break.
3. See whether the hen is only visiting that one box, or whether she has access to several boxes but chooses one in particular.
4. Check if the box is overly bright, crowded, low, or tucked into a spot where eggs may be more disturbed.
5. Watch the flock to see whether another hen is laying badly, treading eggs, or causing stress around the nesting area.
6. Look for signs that the hen is simply pecking at broken egg contents rather than actively opening intact eggs.
7. Check whether the hen has enough to keep her occupied, especially if she’s been dull, restless, or spending a lot of time near the nest box.
Common Causes
The most common cause is an egg that’s already cracked or broken. Once a hen discovers the contents, she can start returning to that box for more.
Another common reason is poor nest box setup. If eggs roll, collide, or sit where they’re easy to damage, one hen may get the habit of pecking at them.
Sometimes the issue is simple timing. If eggs are left too long, one hen may find them before you do.
Less often, stress, boredom, overcrowding, or competition around the nest area can contribute to problem behaviour.
What To Do
Collect eggs more often for a while, especially at times when laying is likely. The less time eggs sit in the box, the less opportunity there is for a hen to sample them.
Make the nest box less easy to damage. Keep it dry, well bedded and comfortable, and avoid letting eggs pile up or roll against each other.
If one box seems to be the problem, try changing its location, bedding or access if that’s practical. Sometimes a small change is enough to break the habit.
Reduce the chance of boredom by keeping the flock occupied with a sensible routine, good space, and enough enrichment for their size and setup.
If broken eggs are found, remove them promptly and clean the area so the smell and mess don’t encourage more pecking.
If the behaviour continues, keep a short note of when it happens, which box is involved, and whether any eggs were already damaged. That pattern can help you work out what’s driving it.
Products That May Help
Keeping nest boxes, bedding and nearby surfaces clean and well managed can make it easier to spot broken eggs early and maintain a tidy laying area.
