I now have 41 chickens, about 15 of them are 17 weeks old, before I got my babies, they all slept inside the hen house, but have always refused to roost, they stay on ground level, and won't settle for anything else, but at least they were INSIDE the hen house. my 7 week old chicks have been outside now for almost 3 or 4 weeks, and they chose the other side of the hen house but still Inside of it. However, here the last two weeks or so, everyone, and I do mean every single chicken in that coop sleeps outside agains the chicken house, they all huddle together like they are cold. Each night I shoo them into the hen house, move the door over the opening of the henhouse, (which leaves a small amount of room for them to get out in the morning. And 15 to 20 minutes later they are all outside again. I know here in Texas its starting to get pretty hot, but I go inside the hen house and its always at least 5 to 10 degrees cooler in there. Soon my older girls will start laying, and I know that if they are already snubbing their noses to the hen house, there is no hope when they start laying. Any suggestions...?
