This is their brooder. It’s nice and warm on the floor but doesn’t by any means feel too warm. The larger of the two started having hard poop dried on its butt. I was able to pull some of it off yesterday, the vent still clear. Today it’s a little more crusty.. when I lift up it’s tail I can still see the vent, but it’s not as clear as yesterday. Do I use a warm rag to soften and try to get it off? Anything I can change to their set up? The smaller one doesn’t have any mess on it’s butt.
