We have two Port-a-Hut buildings that we aren't using, but are assembled. They are 10 feet wide and 21 feet long. I'm thinking about converting one of them to a chicken tractor, cover over the open end with wire, put in a door, build up a false floor in the back for nest boxes and perches. I'm looking for ideas on how to do this. I did find the game bird page on here with the coops build out front, but our Port-a-Huts are significantly larger and we won't be building a front pen. Anyone know of any links or has anyone done this? Thanks!
