Hello, thanks for all your help to date! My Chicken has two round brown red scabs on the bottom of her foot. I’ve taken the top off however there’s no yellow core to squeeze out. I’ve pushed and looked and nothing really comes out. Looking on the top of her foot, I can actually see some yellow puss through the skin. I put antiseptic on the open wound and bandage them. They are healing over with the brown scab again. I keep changing the bandage and putting on antiseptic. Does anyone have any suggestions? Thank you!
