Hi, I'm fairly new to raising chickens, so I will apologize in advance if there is an obvious answer to my question. I have a flock of 4 girls who free range in my somewhat small suburban backyard. I recently noticed that one of the ladies feet are dry and bumpy. Based upon what I've seen in other posts, she might have scale mites. I prefer holistic and organic cures. I recently read that a concoction of garlic and olive oil applied to the feet and legs might help. Does anyone have thoughts or recommendations? Thanks!
