What should I check if my chickens are pecking at soft-shelled eggs?

Overview
If your chickens are pecking at soft-shelled eggs, the first things to check are shell quality, egg collection timing, nest box setup and whether the flock has had any recent changes in feed, routine or stress. Soft shells can be easy for birds to peck at, so the behaviour is often linked to the egg itself or the laying environment rather than a single cause.
Things To Check
1. Check whether the eggs are soft-shelled, thin-shelled or cracked when laid, and whether it’s happening in one bird or several.
2. Look at how quickly you’re collecting eggs, because broken or left-in-the-nest eggs can teach other hens to peck at them.
3. Inspect nest boxes for low bedding, cramped space, poor lighting or dirty conditions that might make eggs more likely to break.
4. Review the feed and water setup, especially whether hens have a proper layers feed, enough access to water and a routine that hasn’t recently changed.
5. Check for signs of stress in the flock, such as bullying, crowding, moving birds, changes in housing or competition at feeders and drinkers.
6. Look at the rest of the eggs for patterns such as regular softness, unusual shell colour, odd shape or a sudden drop in laying quality.
7. Make sure no eggs are being hidden in corners, under bedding or outside the nest boxes, as missed eggs can be cracked, eaten or attract more pecking.
Common Causes
The most common reason is simply that soft-shelled eggs are easier to break and peck at. Once one egg is opened, other hens may copy the behaviour.
Another common cause is a shell-quality issue, which can happen with diet imbalances, not enough calcium available for laying, older birds or birds that are still settling into laying.
Poor nest box conditions, delayed egg collection and stress in the flock can also contribute. Less commonly, a health issue affecting egg formation may be involved, especially if soft shells are frequent or combined with other changes.
What To Do
Collect eggs more often for a few days so there are fewer broken or exposed eggs in the nest.
Keep nest boxes dry, dark enough and well-bedded so eggs are less likely to crack on impact.
Check that every bird has straightforward access to feed and fresh water, and that the flock isn’t being pushed away by a more dominant hen.
Watch for a few days to see whether the problem is linked to one hen, one nest box or a particular time of day. If soft-shelled eggs keep happening, or you notice other signs such as reduced laying, weakness or birds looking unwell, veterinary advice is sensible.
