Is this size of coop fine for trios?

[Backyard Bob]

I am thinking of making pallet breeding coops for LF trios. Would 35" x 45" be adequate sizes?
Just the coop, not the run! Thank you!

There isn't a black and white answer for this. At that size, their usable space would be affected quite a bit by whether food and water were inside, for example. In your climate, a small coop could easily get too hot in summer. Actually, in your climate, an open ended shelter attached to a run, if positioned to pick up summer breeze and shade but with the ability to block winter wind, would be more than adequate. Maybe you can get some ideas from this:
