My rooster had been limping but getting around pretty well last time I posted, but now he's not walking nearly as much. Also at the top of his legs, right where the feathers start the skin is very red and with bumps or wrinkles. With the last one, these were the first symptoms, followed by these things growing until they were about the size of peas, except one on one leg that grew to the size of a strawberry. It then popped and was full of puss and black stuff. He could hardly walk and the one vet we have in the area that treats chickens couldn't diagnose him. Also, I don't know if this is related, but both roosters had lost a spur in the past. (Don't know if that is a symptom, or if they just got caught in wire or something.) So here's the question; do roosters usually have that wrinkled red skin at the top of their legs or is that part of why he's lame, and does anyone know what could cause or cure this?
