I'm in Utah so it gets cold here really fast and STAYS that way. Our first snow fall was in the mountains in late OCTOBER Anyway, I've got my coop ready for the cold! I got all the materials, for free! I got some thick(THICK!) Cardboard boxes from the grocery store and just nailed the pieces of cardboard on the inside walls of the coop, I grabbed some extra pieces of plywood my dad has, and put some shingles on them (My dad is a roofer...we have roofing materials handy ) Put them so they would cover the aisle between the coop and the rabbit hutch(Which I'm using to store feed and tools ) So there will always be a patch of dry ground I then got some free tarps from my neighbor and covered the whole perimeter of the coop and the ground surrounding it, I have an electric waterer that keeps water from freezing and I'm going to get a red heat lamp and put it inside the coop at night to keep them warm while they sleep. I also got a piece of wood about 7 inches tall and put it right in the entrance of the coop so the girls can't kick the wood shavings out... I put straw, pine shavings and aspen shavings. I'm pretty sure theres some paper shavings in there too. I forgot. My girls are nice and toasty. I went in the other night at about 10:00pm and the lamp was never turned on, I grabbed my Orpington and she was so warm! Her feet her comb, everything! So that shows that just with the cardboard and the tarp, it kept them warm I guess we can save electricity until the snow actually hits the ground where the people live So there you have it people My free way of keeping my girls warm I'm just bored and wanted to share this sooo...yeah! Oh and PS. My ducks get into the coop too. Even though it is 2 feet above the ground, they actually know how to use the ramp! Cute right!?
