This is our first year owning chickens. We have our ladies in a fenced in yard. We live in Northern Lower Michigan where it gets pretty cold. We did purchase cold hardy breads but we are now wondering if we should provide a larger covered area for winter? Currently the only covered area for them is their coop which is a couple feet off the ground. If it's not necessary would our ladies be happier? Are they going to get out into the yard in winter or will they stay in the coop most of the day? We were thinking maybe a small tunnel covered with clear plastic. Thanks!
