Question

Why does a hen become aggressive when she is hatching her eggs?

Answer 1

Explanation:

You want to mark each egg because hens will steal other hen's eggs to add to their clutch and you don't want her adding too many unfertilized eggs and not having room to incubate the fertilized ones. ... If your hen is being aggressive, it might be best to wait until she leaves the nest to eat.

Answer 2

Answer:

Explanation:

I have never had a depressed hen from the loss of eggs or chicks. But, some times you will have a hen determined to hatch, it can sometimes be a very strong instinct. Don't beat your self up so. Taking the eggs is nothing to feel guilty about.
