We are wanting to make some revisions to a coop and need input. Our second coop has two solid doors on the front. Because these doors being closed would make the coop far too hot during our summers, we have a screened door for 2/3rds of the opening and intend to build a frame, covered in hardware cloth for the other 1/3. The solid doors will remain open pretty much all year round -night and day - except in cases of extreme bad weather and the coldest of winter days. My question concerns the screen door. It's a very nice (read:expensive) screen door, with the screen built into the door, not inserted with rubber holding it in place. We are unsure whether it will be necessary to cover the screened portion of this door with hardware cloth. Given the fact that the bottom of the screen will be at least 4 ft. off the ground and there will be no trees or other things that a predator could use to climb up on nearby, should we remove the screen and cover the opening in the hardware cloth instead? I don't think using both the hardware cloth and screen is an option. Between the heavy duty, close weave design of the screen and the small diameter of the squares in the hardware cloth, it would pretty much cancel out the whole reason for having a screen door in the first place; which is to allow maximum air flow. Opinions?
