Hi, I have a Brahma broody hen that has about 16 eggs due to hatch on March 12/13. This morning I went in the coop, and she had yolk on her face and there was a part of an egg shell on the ground half way under her chest. I don't know if my other hen tried to push her out of the nest, or what? (My other hen wants to sit as well, but the one thats sitting won't let her) Is there anything I can do to get her to stop? Thanks!
