Overview
If your hen is sitting in the nest box all day, broodiness is one common reason. It can also happen if she's laying, trying to lay, feeling unsettled, or not quite herself, so it's worth checking a few basics before assuming it's only broodiness.
Things To Check
1. See whether she's actually laying eggs regularly or has stopped laying altogether.
2. Check if she's fluffed up, pecking at the nest, clucking more than usual, or resisting being moved.
3. Look for signs of illness such as droopy posture, reduced appetite, diarrhoea, weight loss, or unusual quietness.
4. Check the nest box for warmth, poor ventilation, damp bedding, or heavy soiling.
5. Make sure she can get up and down normally and doesn't seem sore or stiff.
6. Watch whether other hens are crowding her, bothering her, or blocking access to feed and water.
7. Note how long this has been going on and whether it started after a change in weather, routine, or flock layout.
Common Causes
Broodiness is the most common reason. A broody hen often wants to sit on eggs, stays in the nest box for long periods, and may become more protective or reluctant to leave.
Another common cause is simple laying behaviour, especially if she's trying to settle before or after laying. Some hens also spend extra time in the nest box if they're uncomfortable, unsettled, or being disturbed by the rest of the flock.
Less commonly, a hen may stay in the nest box because she doesn't feel well, is weak, or has a problem that is affecting her normal routine. If the behaviour is new or comes with other signs, that needs a closer look.
What To Do
Start by watching her closely for a day or two and note whether she's eating, drinking, and moving normally. Make sure feed and fresh water are easy to reach, and check that the nest box is clean, dry, and not overly warm.
If broodiness seems likely, try to reduce what keeps her settled in the nest box, such as leaving fake eggs or sitting eggs in place. Keeping the coop routine steady can help you judge whether the behaviour is changing.
If she's leaving the box to eat, drink, and move around normally, she's often just being broody. If she's staying put, getting weaker, or showing other worrying signs, contact a vet for advice.
