Shed-to coop-to shed transition ideas? Suggestions welcome

[Biologrady]

Have four four-week olds at the moment, and will soon be transitioning them from a huge dog crate in my garage to outside. My last batch of chicks are living the good free-range life at my moms place, and these girls will join up with that flock in the fall. In the mean time, I thought it would be brilliant to build a shed (from a kit, and we need the additional space) and use it for the chickens for the summer....now I'm realizing it's really going to be getting hot in there! We've already got fixed windows installed, caulked and nailed (and they're in a bad spot high on the walls, if I just screened them and it rained it would be a big mess). I'm thinking about installing a frame that would be screened with chicken wire or similar, and positioned as sort of an inner screen door, so one of the double doors would be fully ventilated, but the outer door could be closed over it in bad weather or if I got predator paranoid. The 3x4x5' crate will be within the shed anyway, and it's lined with hardware cloth to prevent interested paws.
Anybody else have a part-time coop? I welcome suggestions. I love having chicks in the spring, but I may have to hold off next year or more since I don't think I can eat eggs fast enough if our flock population keeps doubling

Even that one door turned into a sort of screen door may not be enough to keep it cool enough for them in there. They need a good breeze along with cool shade to survive in the summer, since 100 degrees F is considered lethal.

During the day they'll have access to outside, and shade...there's a vent hole that's actually perfectly sized and positioned as a pop hole, so my plan is to have them access their crate-in-a-shed through that during the day, and I'll shut them in at night. Just concerned that if we have a really warm spell I might need to keep that screened side exposed and hope it will keep the coons out.

Why not add 1/2 inch hardware cloth over the screened part.

Probably wise. I'm also realizing that I'm going to need to open the coop doors before the sun is up too long...

Coop almost ready! The chickens approve of the yard and ramp...tomorrow we move their crate out to the shed. It will be nice to get the garage back.
Since school is now over I am SO looking forward to having my morning cup of coffee with the girls in the back yard!.
