Never thought i would be cleaning a chickens butt, but i did today........i used warm water and got most of it off. I had to use some little siccors to get the rest off. It was Urainy and a little cooler today so i put her back in the brooder to warm up and dry off. I will probably leave her in thier for a couple of days with some week old biddies i got a couple of days ago. Why does this happen?
