The only time they spend in the roost part of the coop is from when they put themselves to bed until they get up in the morning and walk into the run. They are never locked in the roost at this point. When I or my wife get up they are let out of the run and free range the backyard all day unless nobody is home. So, heat in the roost part isn't a problem cause the birds aren't in there except to sleep.
The coop has a footprint of 5'x10' and the front is 5.5 feet tall. I decided against making it tall enough to stand up in to keep it less visible to neighbors. The roost is 1/3 of the footprint. I'm using sand on the run about 5 inches thick. It's made out of 2x4's with cedar pickets set horizontally for siding and shade. I cut lap joints in the pickets and cut little 45 degree angles on the long edges for looks. The roof is 7/16 osb covered with asphalt shingles. We painted the coop with stain but the color turned out to be whiter than we wanted. The color works for us but we're still fixin to accent it with a darker trim paint.
Thanks for the compliments. This is a first for me. The only way I was able to do it was looking at the way others have done it on this site.
Thanks for the information now my wife just requested blueprints is all. I don't know that she trusts me to try to build it just from the pictures. That is a great looking coop, and I figure if it can stand Southern Utah I can get it to meet Northern Utah requirements with just a few adjustments. I think I will have to show her I can build it. I will look through all the photos you guys have posted.
