So my Columbian Rock rooster has been limping for months now. It began when i moved the pen and took him and the hens out. When it was done i put him back and he flew from my arms and half flew half fell to the ground maybe three feet down. i found out later that he had bumblefoot, I took care of it and he still limps. His ankle is swollen and he limps on it-not severly, but he doesn't run like the hens, he does a funny gallop so as not to put a lot of pressure on his leg. It has been months now, and he still isn't better. Any suggestions?
