We are under a freeze warning for Tuesday night. The overnight low temps at or below freezing. My chicks are 6 weeks old now, have been living in their coop for 4 nights now with no heat lamp. I do have the coop insulated. It has only been dropping down to 40's at night. Everyone seems to be doing fine with 40's but I'm worried about the freeze temp Tuesday. I'm wondering if I should break out their heat lamp from their brooder and hang it in the coop. Problem is I dont know how low to hang it. I really cant bring them back in the house for the night. The brooder is all put away and I'm not getting it back out.
