Hi everyone, I have read through some of the other posts about this, but because I am a worried mommy I must ask my question. We have 6 chickens. 3 Barred Rock and 3 Austrolorpe. They are very sweet, but lately I've been noticing one of them "Billie" has been a little left out of the sleeping huddle. All of the girls roost up high in the coop, but it seems that they are running out of room to all fit. Billie has taken to a lower roosting spot and been there by herself sleeping for about a week. Now, it seems that she is always by herself and is acting really subdued. This morning she was all puffed up in the corner and shaking a little bit. It's been getting chilly at night and I think she may be cold by herself. There are no signs of physical harm to her by the others. I just feel like her little chicken feelings are hurt. Should I intervene and make the sleeping roost bigger so they all fit? Should I be concerned? I am worried for her... Any advice is appreciated!!!!!
