I have a four month old banty wyandotte and I noticed early on that it had a really wide stance. But in the past three days, I've noticed both legs seem to hyper-rotate like they are popping in and out of socket. Today, the poor little bird was obviously having a hard time walking and resorted to hopping. I felt both legs, checked for physical causes and I'm at a loss- I don't even know what search phrase to use to narrow down what I might be dealing with. Thanks.
