We got this little buff orpington from the local feed store a few days ago. They have been having issues with him not feeling too good and had him separated. They put them back in with the other chicks but they were picking on him cuz he was smaller. They offered to give him to me to see if I could nurture him back to health. he seems to be eating and drinking okay, just can't walk well. He needs to use his wings to help him along. It looks like his joints on his feet are swollen maybe? The top of his feet where his toes meet. I'm not sure if there is something I can do to help him walk easier
