I have a hen that hasnt been able to fully stand for over a month. When she does walk, she is very unstable. She eats alot. She comes to me every time I go out there. The other chickens actually seem to protect her. I started treating for vit b deficiency because I read on another thread here someone else's hen was walking the same way and it worked for them. But today I noticed her droppings are very watery and more green than normal. Could it be from the vit b? I have one other hen that has had a head twitch pretty much her whole life. I've been treating her as well. I dont want to put Noodle down, but I think I may have started treatment too late (if it is a vitamin deficiency). What else could this be? They're silkies. About 17-20 weeks old. I spoke with the breeder. Shes never had a case of mareks. There is no lice or mites. I have not dewormed. I have 6 birds i got from her at the same time. I tried adding a video of her walking and it wouldn't let me. I can post it on my Facebook or Instagram or send it to anyone who may be able to help me.
