Here is a video of her. I have brought her inside to rest and alleviate stress due to extreme temperatures. Any help with what anyone thinks might be causing this or what I should do would be immensely appreciated. The entire flock has already had avian pox so I have ruled that out. No one else in the flock is displaying any symptoms like hers either.
