UPDATE:
I the two hens he came with have scaly leg mite so I started my treatment for that. The scales on his feet are peeling off right now like dead skin does on my feet. I treated the rooster the same as I did the hens for scaly leg mites and added a little extra apple cyder viniger to the water. Hoping to pick up some tart cherries to give to him, to help with the gout if that's what it is, and I will pick up some new feed ASAP. I think he is just over a year old not to sure, and as to what he was feed before no idea. the swelling in his feet are hard and its just in his feet nothing on his legs, and no wounds. (gave a bath and trimmed feathers to get a better look.) He has feeling in his feet though. Discovered that when I took a pin to a part of a toe. I poked just enough to get the tip in to see what would come out or if anything wood. All that came out was a tinny amount of blood so I think its free of infection inside as there is no discoloring either. Yes he is missing a toe nail, to me though it looks like it broke off but one of the hens had one to and I had to remove one of her because the tip of her to was frost bit bad and rotten with a tiny infection. Once the nail was removed the infection was removed it was just tiny I treated it and wrapped it.
