Hi there! We just got our first 8 chicks yesterday and I am working on planning our coop. We live in Vermont on 5 acres near Mt. Mansfield so it gets really cold and we have everything from fox to bear regularly in our yard. My biggest concern are bears. We have acreage but most of it is wooded and we have neighbors quite close so typical free ranging is not happening. I like the idea of chicken tractors but I don't feel they are warm enough or rugged enough for predators overnight. Has anyone ever had a permanent coop for nighttime but moved the flock into a "tractor" for foraging during the day? I would like to give them a limited foraging experience for their benefit and also the benefit of our yard. Any ideas or suggestions would be great!
