The new coop will have a covered run. This will be the smaller safe place for them, but they will still free range in the orchard during the day. It will be a minimum of 120 SF, but I'm trying for larger than that. It's all about space in the already fenced area without removing any trees.That should work. Having a floor in the coop is a great idea. My old coop had a floor in it. I elevated my second one. The area under the coop is always dry and provides a constant source of dirt for dust bathing. They hung out there all day today in the rain.
