Sitting hen poked hole in almost ready to hatch egg?

It's very possible that the hen poked a hole in the egg. This is a common behavior, especially when the eggs are close to hatching.

Here's why:

* She's trying to help: The hen instinctively wants to help her chicks hatch. She might peck at the eggs, particularly if she hears them chirping inside, to try and encourage them to break through the shell.

* She's anxious: Nesting hens can be very anxious, especially as hatching day approaches. She may peck at the eggs out of nervousness or frustration.

What to do:

* Observe carefully: Watch the hen's behavior. If she seems to be gently pecking at the egg, she's likely just trying to help.

* No intervention: Unless the hole is large or the chick is struggling, there's no need to intervene.

* Keep the nest calm: Maintain a quiet and peaceful environment around the nest. Disturbances can stress the hen and lead to further pecking.

* Larger holes: If the hole is large, it might be better to remove the egg. This will prevent the chick from becoming dehydrated.

* Contact a vet: If you're concerned about the hen's behavior or the chick's health, consult a veterinarian.

Remember, most hens are excellent mothers and know what they're doing. Let nature take its course unless you notice signs of trouble.
