i dont pin my chickens up at night, they have a run attacted to the coop. They wont use their roosting pole. They want to sleep in the doorway into the coop. And then in the morning their bottoms are a mess from poo. I thought maybe their roosting pole wasnt high enough so i had my husband raise it up to about 1.5-2 feet off the floor and they still are not wanting to use it. Any ideas?
