You don't want to add vents from the bottom front (just like the starter loft from Redroseloft.com)? I think with that there is a better air circulation because it can have like a chimney effect. It sucks in fresh, cold air from the bottom and the warm, stale air gets out from the top.
Yeah, have to paint it yet. Going to paint it the same color as my garage in the background. maybe I'll even put 2 vents in on the front, under the aviary along the floor............. have alot of ideas what I want to do to it yet. Just picked up a young White homing pigeon Friday, came from a really good pair of Birds. the mom was a Checkerd & the dad was all white with red saddle on the wings. The Mother always throws 1-pure white no mater who she paired with. So, I'm hoping this youngster is a male, I have an extra Female here that needs a mate.
