2 year old Ameracauna rooster limping. Have treated many times for bumble foot with epsom bath soak, removal of scab and stringy pus substance, stuffing hole full of neosporin ointment and Vetricyn, and wrapped/retreated with neosporin/vetricyn for at least 2 weeks afterward until all cleared up. Now it appears bumble foot is back and the scales on his lower legs and coming off/cracking amd bleeding. No other chicken even has bumble foot and we have 80 of them. Any suggestions? Am I missing something here?
