Hi. I have a new 7-week old pullet/chick and four adult hens. The little one is hiding under the coop. I can't get her to come out, and the big girls are not being nice to her. When we first picked her up, I noticed some feathers missing from her tail area, but once we got her home (before she went in with the big girls) I saw it was a bigger area of missing/broken feathers and there is blood on her tail. She's obviously been picked on before, and doesn't want to risk it. I'm worried that she's not going to get enough food/water to keep herself healthy or alive eventually. Recommendations?
