My 11 pullets and two roosters are 12 weeks old and until yesterday, they were roosting either on the roosting poles inside the main coop or on a 2x4 near the top of the open part of the coop. However, last night they were all crowded together on a shelf and then again tonight. There are raccoon all around which is why I used 1/2 inch hardware cloth on all openings. All the doors close with spring latches and have only 1/4 inch gaps. I even checked with a flashlight tonight to see if there were any snakes or rats that had somehow gotten in, but there wasn't anything there. I guess the raccoon have been trying to get in. Good luck with that masked bandits. I used extra staples.
