Last night I found one of my girls sitting in one of the nesting boxes. Once I looked at her I noticed that her comb had fallen over, which isn't normal for her. She's been lethargic and I haven't seen her eat or drink. I've separated her and have been treating her as if she was egg bound. I just checked her vent, and I couldn't feel anything. So I'm at a loss. Does anybody have any suggestions on where to go from here?
