I was told my chicken has bumble foot but I don't have a plug. The pad of my chickens foot looks like a cracked callus and is split sorta into three different parts with a hole in middle. Where would I look for the kernel or infection. So far I washed it and put some rubbing alcohol on it cause its all I had on hand last night. I plan on messing with it tonight I just don't know where to dig the gunk out of her foot and don't want to cut into her foot with out a plan. This will be my first time doing any of this.
