My in-laws went and checked on our hens today and they called me and told me we have an extremely lethargic Rhode Island Red. She is under a year old. She was fine when I saw her last (2 days ago). They said that she was laying on the floor with her eyes closed, so they went over to her and picked her up and put her in one of the nest boxes where she stood for just a second and then went right back to sleep. They also mentioned she had some feathers missing. I assume that this is because the other birds were picking on her because she was sick? We have 24 hens. None are roosters and it has been probably a month since we got any new birds. They have a timed light in the coop so I don't think there is any molting going on. I have read a couple things that range from an impacted crop to just needing dewormed. We are separating her from the rest of the flock. Does anyone else have any thoughts? I'm worried about my poor girl!
