I have a white aracuna chicken about 3 months that walks funny. She stands sort of like a penguin: head very high, tail nearly on ground. When I pick her up there does not appear to be any problems with her legs, they move just fine. As I move them she does not appear to be hurting. Looks almost like a pup scooting on their butt when they have worms. This just recently started. Vent looks normal. Can anyone tell me what the problem is and is there anything I can do for her?
