my 8 week old chicks were put in my new coop and run yesterday. I put them all inside last night and they don't seem to want to get on the roost bars. I put some of them up there so they would get the idea. Ever since going into the run they have stayed under the coop steps. Why are they doing this and is it normal? Do they need something to get under in the run? Pics of the setup and the chicks under the step.
