I have 2 Buff Orpingtons who are 3 weeks old and they are acting weird. They are burrowing down in their litter and then laying out on their sides. The other Orpington isn't doing it and my Barred Rocks aren't doing it. I've never seen my chicks lay down this way before. Are my chicks okay? Are they over-heated and cooking in their brooder? Are they ill? What do I do???? I don't want to explain to my kids that we lost a chick because Mommy cooked them by mistake! Please help!
