I saw chicken yesterday sit on the floor with poo.... instead roosting or in a clean nest box. There are six clean boxes with straw and they only use 2 boxes. Does anyone think they know a chicken would nestle down on the poo in the floor? This is the first time I've seen a chicken do that. During the day they have access to dirt and she didn't look like she was taking a dust bath. It was night but we had the light on in the coop. Thanks for any imput.
