I’m fairly new to chickens and my silkie rooster has been getting picked on by his hens. They’ve been plucking at his feet to the point of bleeding and we have cleaned him up and put antibiotic ointment. However yesterday we noticed he was not walking around like he normally does and decided to peak at his feet again to find black spots all over. I began a soak yesterday and today with Epson salt with iodine. I tried with a tweezer to get these black spots off however they are flesh with his skin and I was unable to. Any tips, suggestions, advice? I feel terrible for him.
