Hi, newbie here, been to several things today on google and can't seem to find what I'm looking for. Several of my chickens seem to be developing a scaliness to their feet and fore legs. About 3 months ago I had a roster that I tried to treat with the same thing by cleaning well and using first blue spray the scarlet oil, both to no avail. He just got worse and worse and I ended up having to put him down. Then this morning when out tending to my crew, I noticed several of my hens are getting this "scaly" look now too. Please help, is this some kind of fungus? I live in Florida in the Panhandle, does climate/region have anything to do with this?
