Well, everybody has been roosting wonderfully on their roost night after night...until last night. We went to lock them up last night and only 9 girls were on the roost. We looked all over the run and couldn't find the other 3. My daughter looked up in the coop and there were my 2 leg horns and one of the BRs up on the 2X4 rafters. One is directly over the roost so the chicks roosting below get pooped on and one is where we hang the feeder from so it was covered in poop this morning!!!! How do I keep them from sleeping there again tonight????
