I know! it is just too cold and I can't seem to leave enough food for them - they are eating pretty heavily, a combo of needing it and boredom I think.-18 out there and my coop stayed at 0 at roost level with the flat panel radiant heater (150 watt) Boy I like that thing. So far so good. I like 0... I can do 0 for my birds. They've done -15 in the coop..but I know they don't care for it. Bracing for tonight too....
