Hey all! This is my first post on BYC My husband & I have been planning for chickens for quite a while, & I actually had plans for a big coop and run attached to the back of our barn. BUT, we had the opportunity to purchase a used tractor coop for cheeeeeeap - allowing us to accelerate our chicken timeline significantly! We will likely still build our larger coop/run in the future, but we want to go ahead and get started with a small flock soon. Anyway, on to my question! I've enclosed a picture of the coop. The only ventilation it has is via the roofing material - the raised channels don't sit flush with the sides, so air can exchange through there. Also, the ramp comes up through the floor, and doesn't have a door of any sort so I suppose that is ventilation, too. We live in the north GA mountains. Our summers are ridiculously hot & humid (I can open the main coop door in the summer), and our winters are mostly mild, with usually one decent snowfall. We very rarely get below zero. I'm mostly concerned about winter. Do we need to figure out some way to make more ventilation for the coop? Thanks for sharing your expertise!
