Hi everyone, I have a hen who seems depressed. She is a RIR/White leg horn cross. In the last few days I have noticed that the feathers around her neck are missing/damaged, as well as her tail feathers. When I open the coop, all the other birds (5 other RIR/WLH and 2 Speckled Sussex) come sprinting out and she just lingers in the pen/coop. I have been watching to see if anyone is bullying her. I haven't noticed any inappropriate behaviors toward her. I have 8 birds total in a coop that can fit up to 20 birds, so I don't think crowding is an issue. I let the birds out as often as possible but I do have a full time job so their free ranging time is limited to weekends for the most part. They have a large pen off the side of their coop which I put scratch or other scraps in each morning. They have access to food and fresh water continuously. All my RIR/WLH girls did have their beaks clipped when I got them. Hers is a little flat/rounded at the end but I have seen her pick up pieces of scratch so I don't think its keeping her from eating. I'm really worried about this girl. I have never had an issue with hens but I know they are social creatures and she just seems sad, lonely, and not thriving like my other hens. Can I have some suggestions as to how to proceed forward?
