I put my 8 week old Australorps out in the coop yesterday and they seemed to weather the first night quite well in spite of the temp getting down to 27°F. I set up the IR lamps to create a warm spot--it's maintaining 52°F although it's still only 28° outside. I expected them to huddle under the lamp as it would be the place closest to the 60° they've been in for the last 2 weeks but they are doing normal chicken stuff throughout the coop and seem to prefer the cold, dark north end of the coop near the nest boxes. Everyone seems to be content and healthy but I wonder, will chicks this age seek out heat when they need it or do they lose this instinct? I'm continuing to watch them closely and check on them through the window every hour or so.
