I think I have a rat picking feathers off my ladies at night while they are roosting. I haven't been locking the coop at night and just shutting the run door. Apparently, that wasn't very smart. Last night I went out to shut the run and fill the feeder and what I think was a rat came running out of the coop. They have been missing bum feathers for awhile now. I just thought they were doing it to each other. Do rats feather pick? I am going to start closing the coop!!!!
