I am so frustrated... after trying several kinds of roosts (now 2x4 flat side up) only 2 of my 11 chickens use the roost. The rest sleep on the raised wood floor in the pine shavings. They dig holes, roll around and cover themselves..... Is this normal?? I know they like to dust bath, but they like to do it before they sleep and then they settle down and sleep in the holes that they dug. I just went in there to snap this picture, you can see they are all snuggled up for bed.
