Every time my chickens (4) go to sleep they all go on their roosts, but later in the night one of my pullets get pushed off and ends up sleeping on the floor. We have 6 roosting posts (3 on one side of the small coop and 3 on the other) The roosting posts are quite close together so they can lay across three posts at once. The pullet that gets pushed off is extremely docile so doesn't mind sleeping on the floor but then she gets crusty feathers below the vent to her legs. What can I do, I really have no idea!! Also, I can't put two chickens on one side and two on the other to make space more even because they all like to huddle up which is so irritating as they can't even fit all of them in the roosts This is how the nights are usually sorted out by the chickens. (They could all probably fit on the roosting pole at the time but they grow so fast!
