Does anyone know what this is?: New Year's Day, my 1 1/2 year old Silkie hen was found sitting way back with left leg forward and out. (I noticed her sitting not quite right the day before, but when I disturbed her, she got up and walked away just fine. She is a very broody bird, so sitting is common.) This time she was very unbalanced and had trouble walking. I picked her up and noticed she was very thin. She also appeared to have an ear infection, her right ear clogged with exudite. I cleaned her ear and began hand-feeding her, supplementing her usual Layena with soaked dry cat food and scrambled eggs and water, and vitamin E. She was getting stronger over the next several days, sitting more forward, eating voraciously, especially when offered a now-daily cat food and egg breakfast. Then yesterday something changed. Both legs are splayed forward and she can not support her weight. She can flex her toes slightly and can move them a little in a slow walk if I hold her up. Ears look pretty good, no more clogging. Any ideas?
