We are starting our first flock (since I was 8 anyway) and our 15 little ones are going on 3 weeks. So I am starting a coop and have the general idea of what I want and have just a few sticking points I need help with. I have taken an old trampoline that had the surface melted (careless yard fire...long story) and split it in half. Using an old TV antenna pole used the leg holes at what is now the top to make a cross bar, which gives it a greenhouse look to the overall frame. (I'll try to post pictures once I figure out the site.) I have an old house that is falling apart that I am salvaging materials from to build the actual coop. My plan is to use the siding from the old house to cover the walls of the coop, but can't quite figure out how to join them at the top, since it is a metal bar. Any ideas?
