I have a 3 1/2 yr old hen that is standing with what looks like spraddle leg, like a duck, and her her tail end is down like a penguin. SHe is walking around, but I was'nt home today so I'm not sure if she ate or drank. She did fly up on the roost. Does anyone know what might be wrong with her? I did notice yesterday she was standing with her head under her wing out in the lot, in the middle of the day.
