I have an old Barred Rock hen, and a couple of days ago I found her in the coop laying on her side. I thought she was dead at first, but then she started to move. If I help her to her feet, she is a little unsteady at first, but is able to stand and walk around on her own. One of her feet looks a little swollen, and like there might have been a little dried blood between her toes. I didn't see any wounds though. I had also wondered about arthritis, being that the last few days have been colder. I could use some advice on how to help her. She is eating and drinking normally. She just can't seem to stand up by herself, and is walking slower than normal.
