This box is getting a bit messy. The rooster must be a male. (That is not a sexist comment. I have observed on many occasions that males poo in the box when they roost, but females don't. This makes good sense as females roost with their chicks overnight when they are incubating and when the eggs first hatch out, and pooing in the box in these circumstances would not increase the chicks chance of survival!)

Tucked up for the night.

Just in case the rooster left the box later, I took another picture well after dark - and he was still there!
