Overview
Egg eating in chickens is usually worth taking seriously, but it does not always mean there is a medical problem. In many flocks it starts as a habit or a response to broken eggs, stress, overcrowding, poor nutrition or boredom. You should call a vet if the behaviour is new and persistent, if several hens are affected, or if you also notice illness, weight loss, reduced laying, poor shell quality or any signs of injury.
Things To Check
1. Check whether the chickens are eating whole eggs, pecking at cracked eggs, or only taking interest after an egg breaks in the coop.
2. Look for shell quality problems such as soft shells, thin shells or misshapen eggs, because these can make eggs easier to break.
3. Check the coop and run for overcrowding, lack of nest boxes, or nest boxes that are too dark, too bright, too high traffic or too hard to access.
4. See whether the flock is short of interest, space or foraging opportunities, especially if they are confined for long periods.
5. Check the hens for signs of stress, bullying, feather pecking or changes in routine, including new birds, moved housing or reduced turnout.
6. Look at the diet and feeding routine to make sure the birds are getting a suitable complete feed and access to water at all times.
7. Check whether eggs are being collected quickly enough, especially later in the day when breaks are more likely to be noticed and copied.
Common Causes
The most common causes are accidental breakage, repeated access to broken eggs, boredom, stress and a learned habit that spreads through the flock. Poor nest box design, limited space and feeding routines can all make it more likely.
Sometimes egg eating is linked to shell problems, such as thin shells or brittle shells, which make eggs easier to crack. Less commonly, a hen may be unwell, in discomfort, or laying poorly for another reason, so it is worth paying attention if the behaviour appears alongside other changes.
What To Do
Collect eggs promptly and remove any broken ones straight away. Make nest boxes comfortable, quiet and easy to use, and try to reduce crowding and competition around laying areas.
Keep the flock busy with normal foraging and enrichment, and make sure the diet is appropriate for laying hens. If you can, watch for the first bird pecking at eggs so you can work out whether the behaviour is starting with broken eggs rather than true egg eating.
If the habit keeps spreading, keep notes on when it happens, how many birds are involved and whether you are seeing any other changes. That information is very useful if you do need veterinary advice.
When To Contact A Vet
Contact a vet if egg eating starts suddenly and doesn't settle with basic management, if more than one bird is involved, or if you also notice reduced appetite, weight loss, poor shell quality, diarrhoea, lethargy, breathing changes or signs of pain. A vet can help check whether there is an underlying health or laying problem rather than a simple learned habit.
Products That May Help
Keeping the coop clean and organised can make it easier to manage broken eggs, collect them promptly and maintain a calmer laying area for the flock.
