It was 25* this morning at 7 and I had put heaters in all the coops then stapled plastic bags over the doors. Checked on them last night before bed and they were nice and warm. Checked this morning and all were fine. I didn't let the babies out of the coop this morning. Will do so when I get home and it's warmer. All the water we left running had ice hanging from it this morning. The horses had licked a hole in the ice to get to the water. But we should be back in the 70's by the weekend!!
