We are building a Chicken Coop! She's 71 years old and 98 pounds soaking wet. I am over 50 years old and over twice her size. We are using recycled materials that she selvaged from a 14x64 Mobile home that she disassembled all by herself. We started from the ground--- up. It will have all-season gable end vents. Both sides also have vents all along the length that will have hinged covers for winter and foul weather. There is a full length window beside where the people door will be. The whole thing will be wrapped in recycled siding from that infamous mobile home.
