I have two 6 month brown leghorns in a 4x4x8 coop with two levels. They spend all of their time on the upper level. We are putting in a new (wider) roost for the winter, and I'm wondering how far away from the heat lamp it should be. I want to make sure they are warm, but I don't want to roast them. Also, what temp should the lamp be? I read elsewhere someone using an electric panel heater- would this be a good option to keep them warm enough? Right now they spend most of the day in the yard, but at night we put them inside. Winter temperatures will get close to zero once in awhile- mostly in the teens. These chickens have become part of the family. The first thing my 9yr old dd does every morning is to run out and check on them. I want to be sure they make it through the winter. Thanks, Susan P.S. Thanks to all who have posted advice on caring for brand new chicks. Our chicks wouldn't have made it without you!
