I put a flake of hay in their run,it takes them about a day to rearrange it. Each day I throw in scratch, and other treats so they have to find it under the hay. it does keep them busy, and helps keep them warmer. My run only 5X10, and I only have four hens for now.
I am in North Carolina, and we have never seen what you are dealing with. I wish luck.
