Mine go to bed after the sun goes down but before dark. I have a few stragglers that like to take their time. I have to time going out to shut the door just right. If the stragglers see me and they are not "almost in" they come running over hoping for food or treats and it takes forever to convince them to go in. I throw scratch in the house before shutting the door so they help with the mixing of the deep litter. If it is too light or some haven't roosted yet, when I throw the scratch it causes a scene and chickens are squacking and jumping down so they don't miss their share. You can't win! Sometimes after a hard day in the yard I want a hot, soaky bath and don't want to wait until dark so I try to shut the door early. The girls seem to have other plans.
