I guess it could be called a chicken tractor, as it will be moved around. I worked outside all day Wednesday building the chicken pen. Here is what I started with: We found 2 of these outside of a business by the dumpster. We asked about them and they said to take anything out there, it would save them the trouble of hauling them away. Here are pictures of the finished chicken pen: Look at that chicken!! Brandon got in to fill the nesting boxes with wood chips More pictures: Nesting boxes and roosting pole The chicks in their new home. If you look to the lower right side of the picture, youll see the guineas looking in. Thats about it. We put the chicks in the pen for the first time yesterday, and they are still there this morning! I worried that something would come eat them in the middle of the night.
