My grandson and his mother decided that Meme and Dada needed some chickens. I am currently in the process of reconfiguring the wooden playset into a chicken tractor. It will be heavy enough to resist bears! The worst it will have to resist is a pair of 40 to 50 pound dogs. It will also have to be mobile. Current plans are the coop will be 48 x 54 inch with a high side height of 5 feet. I am also going to build a storage/future brooder on one end. The storage area is 48 x 28 inches, full height. A run of 6x6 feet, covered will extend from the side. All will be covered with corrugated metal roofing. I am trying to reuse all wood from the playset, only purchasing the wire mesh. The build is my enjoyment, the chickens are for the rest of the family.
