this is a chicken coop that I built at school it is eight by six and the hoops are ten foot long pieces of rebar. the base is free angle iron that was donated to our schools welding shop. The end of the coop is a light duty diamond metal mesh that was $65 for the entire sheet. The hoops are attached together by a 1/4 X 1/2 piece of metal. There are three of them spaced every 32 inches apart.
