Coop building time again. I had help the first time but this time I'm on my own. Question # 1: When I see these coop designs with nesting boxes that you access from outside the coop by lifting up a lid, what do you do framing wise to support the nesting box? I'm not getting that. Even the pictures people post here, I've looked at for hours and hours now and I can really see enough to figure out how to build it, I need it really broken down into the simplest detail. Question #2: The first time around we used nails because my boss had an air nailer. Now I don't have that. Can you tell I miss my boss (and his air nailer?) Can I just frame with screws and use my drill? If so, what kind of screws should I get? Thanks in advance.
