I've been working on my coop for the last few weeks and have been planning it for several months. I've always planned to use the solar grey acrylic roofing panels because I liked the idea of the natural light. Well today I managed to get in a good day and finished the siding and cutting out the windows and doors, did some trim work and got to the point of being ready to put on the roof. I went to Home Depot get the supports for the acrylic panels and to see how many I could fit into my Prius. So I'm looking at them and 12 foot solar grey are about $32 each (I'm gonna need 7). Plus about a buck each for the supports---another $35 or so. Right under it is corrugated tin. Twelve foot sheets of that are about $13 each and I don't think I would need nearly the same number of supports. Suddenly the diffused natural light coming through the roof didn't seem as vital... The coop is 12x8 divided into an 8x8 coop areas and a 4x8 storeroom. There is a window in each section about 2x21/2 feet. The door between the two rooms will be a dutch door with the upper part essentially a frame covered in 1/2 inch hardware cloth. There's also a door for cleaning under the roost area and the pop door as well as the solid door to the store room. I'll also add some vents between the rafters. The coop sits in a very shaded area (photo below) so with all that air flow I'm thinking tin shouldn't be too hot. And it's probably $150 less. Anyone have thoughts on one or the other?
