My Chickens are not clipped but they seem to of found a new roost. They go up on top of the Chicken run and want to stay up there. If I did not get them down they would probably would stay up there at night. They did well going into the coop and will go in here if I shut the run door. Door is on a timer and was not working for a little while but now I have to go make sure they are in the run just to hope they go into the coop. Any idea on why they are doing this?
