My dad is very sweetly building a variation on this chicken tractor for my birthday: http://cgi.ebay.com/CHICKEN-TRACTOR...9|66:2|65:12|39:1|240:1318|301:1|293:1|294:50 We're made some changes, but it's still the same basic A-frame layout. Here's my problem. I bought some great scalloped-style shingle panels at my local Habitat Store, planning to use either those or simple asphalt shingles on the roof. My dad points out that using one of those materials will mean lots of nails, which potentially means chickens poking their eyes out, etc. on the points sticking into the house. He wants to use a simple sheet of T-111 (painted) and leave it at that. I have some aesthetic issues with that, since we live in the city and this tractor may be in our front yard at least part of the time. How do you all deal with the nails-sticking-out issue? Do you crawl inside the house and bend them all down? Is there another way to install the shingles? Or another roofing material that avoids this problem but still looks nice? Since it's an A-frame design, the roof comes all the way down to the ground, so whatever we use is going to be the main thing you see when you look at the side of the coop..... Thanks!
