After getting some great ideas looking at the coops posted on Backyard chickens, I started restoring my Gradfathers 1930's 5x10 Chicken coop that was rotting into the ground. I decided to put it up on an old trailer we had to make it into a portable Chicken Tractor. Best part yet to follow the spirt of how it was built during the Depression, I have been using almost all second hand lumber and materials that were laying around or left over from other projects. " I did break down and buy three sheets of OSB for the roof for $30, culled lumber at Lowe's for the deck for $12, and the siding on Craigslist for a $100. I think that the trim for the siding was my biggest expense setting me back about $200, but I think this restoration will last my family another lifetime or two. I plan on using an old 8x16 dog kennel as an attached run but will I have to add chicken wire to the page fencing to make it more secure?
