So I was at tractor supply last night and all of the remaining chicks were half off so obviously I had to get a couple. Once I got in the car I noticed one of the chicks had black toenails of both feet. Is this normal? Ok? Do I need to do something about it? It seems fine I was just concerned and wondering if it needed to be treated somehow so it won’t spread or something?View attachment 2641019View attachment 2641020
