My 4 year old alpha rooster has been limping for a couple of days. When I checked out his foot, a toe was swollen with a scab. I applied neosporin for a few days and covered it with bandaids. Later, I soaked the feet in warm water containing Epsom salt and the scab around the finger came off. I have been applying neosporin and bandaids as usual while giving antibiotics and painkillers too. The limping has become worse. Also, his knee is swollen. Please help, he’s very important to me!
