My whole coop-run if full of snow. I snow shoveled some walking areas for them but its not enough. They have no ground to scratch and peck (frozen) and they hate walking in deep snow. I cleared some walking areas that are maybe 2' x 20' (2). Thats the best I can do. There is no free range area that isnt under 3 feet of snow. So the little pricks are pecking out each others feathers. What can I do?
