I have six hens. In a burst of energy, when I built the coop for them, I built three nesting boxes. Despite the fact that there are three nesting boxes, the girls will only use one! The result is a line-up at the coop.
This morning, Soda Pop was in the preferred nesting box. Johnny-Cade was lined up nearby waiting for her turn.
At least the girls are patient while waiting their turn.
