I have been noticing that there is a LOT of poop on top of the nest box when I go in. Then, I realized that RIR is actually sleeping on top of the nest boxes rather than inside of them. This is unusual because she has always slept INSIDE then, never on top. And why would she? It's freezing out and instead of sleeping in the warm, pine/straw filled box, she chooses to sleep by herself on top of it. It makes no sense to me at all. I thought maybe the other hen who shares the space with her had taken over the preferred box but she has since moved over to another one and the RIR is still sleeping on top of the boxes. Does anyone know why on earth she would do this? She seems fine other than her wierd choice of sleeping arrangements.
