Hello! My name is Liz and I am new to having chickens and need some help with my coop, my chicks are 6 weeks old and need to go outside so the lows in my area are anywhere from 36-46 degrees right now and then go in the 50s but at the time of them going outside I was wondering if I should provide a SAFE heating source (what is a safe heating source????) and hay? I don't want to put a heat lamp with hay and burn the coop down so was wondering if just hay will do because the placement of the heat lamp is not ideal and also can anyone help me with the sex of these chicks, I have a couple pictures of there tail feathers right now Thank you!!
