Yeah, you can leave the windows open for quite awhile yet IMO. Like I said before, I close them at 40 degrees F or lower. The birds could handle lower, but I like to keep them comfortable.

LOL................ I'm just not into buying anything for my birds that is 'ready-made' regardless of the religious affiliation of the craftsman; that's all. Come to think...
I have two very large windows slightly above roost level in my adult coop. I start closing the shutters over the windows when nighttime temps. drop below 40.
I have ventilation at the very top of the coop walls, at roof level, that stay open year round.
