Whenever my EE pullet, Rhonda, lays her egg, she puts shavings on her back. I was curious as to why she does this. Even after she lays, she just sits there and keeps putting shavings on her back. Is she cold? Is she in pain? She sits on the egg, but if I walk up and pet her a bit, she'll jump up to go play with her friends. Also, when my chickens are in the coop for whatever reason they decide to eat the shavings... I have no clue why. They have plenty of grit, oyster shell, food, and water. Any thoughts? And thanks!
