I have a gen who was fine Friday. We went out of town and got home Sunday. Her tail feathers go up like a turkey every time she takes a step. She doesn't roost the last two nights. Her balance is off. I saw this when she ran to me but couldn't stop herself and fell forward. She just lays down. She walks though. She isn't lethargic. Eats and poops. Butt looks fine (easy to see due to her feathers). There's no weird smells. She doesn't stay with her group anymore but she doesn't shy away from them. I found no signs of trauma and there hasn't been any picking. Any ideas? None of the diseases or illnesses I've read on seem to match her symptoms.
