I just got more chicks! I have GLWs, BRs, and BOs (all pullets). Everyone is happy and healthy, and I am having a blast. However, I remember reading (with my last batch of chickies) that when poop dries and hardens on chick feet, you have to pick it off. Have you ever heard of this? I trust Gail Damerow, but this concept seems a little wacko!
