I live in Alberta Canada near the sask border. It is getting bloody cold here. It's not unusual to get -35 here in the winters. I have but a 175watt red heat bulb in the coop, I have 15 chickens. It doesn't seem to be doing much in there. The coop is 100% insulated and polied. I have used the red lamp 3 times and whenever I check the birds at anytime in the night from midnight-4am and they all still wide awake and playing and eating. Any other suggestions? It appears they can see the red light and not sleeping. NO heating is not a option. It gets freezing temps here. Thanks.
