I'm thinking about putting my hoop green house beside the coop this spring, buying a green house tarp for it, so it'll be ready to go for next winter. They had access to it last winter, as well as a "solarium under the loft of their hoop coop. That was nice for them. Always improvements to make.
Quite the impressive pic! Love how you're set up. I'd like to make a covered run before next winter! This year, we barely got the coop closed in before winter, so I don't even have a proper run for them, but they get out to free range a bit during the nice days.
