We have had a couple nights below freezing, 27-29 or so. My adults were fine, the snowies at 5-6 weeks were generally fine, but I had to bring one of the blind ones inside. I suspect her issue was not the cold, just couldnāt find the feed regularly. Itās is so wet here right now, and when the rain lets up I put down new chips, and refill the hide boxes. So far so good. Some of the āpopularā girls are missing a lot of feathers on their heads and necks, but theyāre fine as well. The tarp overhead keeps water from falling on them, but itās so wet, the chips absorb water from the ground. The birds also dig into the cold wet ground/mud and wallow in it which also doesnāt help keep the chips dry. Over all, so far my birds are unphased by the cold.
