Hi all! I know it's still July, but I am already freaking out about the approaching cold weather. I live in MN and last year we had a horribly cold winter. This is my first flock of 5 RIRs and I just want to make sure they are OK. We purchased the Precision Pet Old Red Barn Chicken Coop and built a larger outside run for them to enjoy. The coop has a dirt floor and is rather low to the ground. I don't think the deep litter method will work, as the nesting boxes sit just 5 inches above the floor. Also the coop doesn't have a door from the hen house to the run. It's just an opening. I need suggestions. Do I make a door? Do I put plastic around the whole thing? Do I add a light? What kind of bedding should I use? I want to be prepared for these little ladies to survive the harsh winters we can have!
