This is my first winter with laying hens. Every morning I go outside and open up the pop door on the coop to let the chickens out into their uncovered run. Usually they bolt for the open door and are outside in no time. Last night we got about 1 inch of new snow, so the chicken run ground area was completely covered in white snow this morning. When I opened the pop door, the girls ran to the opening, stopped, looked around, and then did not go outside. It's not a big deal for me as I have all their food and water in the coop itself. So they don't need to go outside. It's been over an hour since I opened up their pop door and not one of my ten hens has ventured outside. I am wondering if next year I should make the run covered, or at least partially covered, to encourage them to get some fresh air outside. They don't seem to like a snow covered chicken run.
