So I've got three new hampshires, three australorps, and four wyandottes in a cage, all chicks. I know that if poop sticks to their butt, you have to use warm water to get it off. I've had three different groups of chicks that lived in the same cage under the same heat lamp, but non of them had poopy butts like this group. I don't understand why they all have dried poop on their butts! Almost five have had it and we've only had them for three days! What's happening??
