I have 26 BO pullets that are 12 weeks old and they are making me crazy! Every night when they go into the coop they all go to this one corner and they just pile on top of each other. We thought maybe they wanted taller roosts so we built those today. Well, tonight we go in to check on everyone and close the coop up and all of the RIR pullets are on the very top of the new roosts and all of the BO's are all piled on top of each other in the corner. Any idea why they are doing this? I'm so afraid that I'm going to go out and find squished babies. Thank you for any insight before this chickee mama loses it!!
