Thank you so much for this post! It's our first winter with our four hens (approx 7 mos old) & we recently had a quick & nasty winter snap here in Wyoming...single digits, below zero at night. Our winters are typically chilly & have lots of low temps, but this came so quickly & we went from 40-50's to single digits. I've been a nutcase worrying about our girls! In all honesty, they don't act very happy about it. Our coop is not insulated, we think it's fairly draft free, & it's well-vented. But it's small & the vents are not too far above where the chickens roost. We do DLM, check them for frostbite (so far no signs of it), have a heated water dish & fresh food all the time. The food & water are under the coop on the ground (actual coop is raised & sits on top of part of the run as a way to provide shelter to part of the run).
Something I have noticed...the birds are not eating nearly as much as they usually do! Do we need to get their food off the ground? They continue to eat scratch & the occasional table scraps, but we used to have to refill their food every other day & over the past few days, we haven't had to refill it. In these cold cold temps, the food is so very important for them to fuel & keep warm! Anyone else notice this? Solutions? Putting their food in the coop would be a last option - it's small & we wanted to keep the food out of the pine shaving deep litter floor.
