I have 4 LO's and 1 bantam all hens. The LO's are 15 mths old The bantam is just about 5 months old. The bantam will walk up behind a LO and stick her head underneath her. I don't know if she has a favorite or if she's doing it to all four of them, she crawled so far under one hen that the lavender ended up sitting on top of the bantam. Why is she doing this? Does she still think she's a little chick and wants a mama? She was given to me by someone who ordered 25 ducks and she came with the ducks. The lady didn't have chickens so she gave her to me.
