I will post pics of her as soon as I can, but the trouble started this evening and with all the fuss trying to figure it out I didn't have time to document it. When I got Gimbly, she was in a batch of chicks purchased from Pistils. We didn't notice her leg deformity until a few weeks later, as we are first time chicken owners and it wasn't obvious. Turns out she likely has leg deformity that Silkies are prone to anyway, on account of inconsistent incubation conditions when she was in the egg. (We weren't involved in that part of the process so we don't know any more than that). In any case, the hope was that if we splinted it she would recover. The splinting didn't work, but she did appear to get around well by flapping her wings, hopping with her good leg, and a sort of "pushing off" movement she uses to get around. She eats and drinks fine, when the other hens give her a chance. I spend extra time with her making sure she gets fruits and other treats before the bigger hens can steal them from her. So now all the hens have started to lay, and we were beginning to wonder how that would affect Gimbly, if she would lay an egg, if she was among our egg laying hens (hard to know who is laying what and when since they all chose the same nest box) or if she would become egg-bound due to her odd condition. Today when the chickens were let out to free range, she stayed in the coop. When I went to investigate she had her head tucked under her body and was frantically distracted by grooming. This seemed abnormal, so we decided to bathe her and check her for mites and other things. We drew her a warm bath, used a small amount of Dr.Bronners, and soaked her until her feathers were clean. Then we rinsed her carefully and she let me blow her feathers dry and made happy sounds later as I was holding her to warm her back up. She showed no signs of mites, scaley skin or anything, though her feet pads (especially the crippled foot) were pink) I thought she was going to be fine, since she pooped normally, didn't appear to be bound up, and looked around interestedly at the house. The moment we put her back in the coop however she tucked her head again and began nibbling away at herself. Is this normal behavior or a sign of something worse? It appears very obsessive for her and kind of freaks me out. I'm rooting for her as the under-chicken, but if there's anything I can do to spare her from an untimely death or discomfort I'd like to know.
