I have a RIR hen that's in a bad way. Maybe starting a week or two ago I noticed that she didn't really roam around with the other hens. She would just stand still with her head sucked down looking like a little ball of feathers and seemed pretty sleepy. She's a little smaller than the others so at first I thought maybe she didn't care for the cold weather much. Then a few nights ago she really started getting lethargic and unable to move much. I brought her in the house thinking that warming up might help, but she seems to be getting worse. Now that I can observe her a little closer here's what I'm seeing: - She doesn't really move at all. She's mostly laying down with her head sucked in or with it under a wing. She seems to have trouble standing/balancing. - She won't hardly open her eyes for anything. If you pick her up she barely even reacts. - She hasn't eaten or had any water, and I'm guessing it's been several days at least. - Her poop is basically water and pretty foul smelling. Looks like maybe one had some solids in it, nothing is goopy or thick. - Her waddles are a pale pink (like human skin color) Thanks for any suggestions. The other hens seem totally fine and this is my first sick chicken.
