I have been working on a bird house for the butler bob breeders. Since I plan on keeping the breeders year round, they need a nice place. This will be the pen set up I have inspected for my breeder license. I will build simpler grow out pens for the spring thru fall birds that go to came before the real winter weather comes. Right now it doesn't have the doors or skids\\legs on it yet yet and weighs over 700lb. Its built like a house. Its 8'x5', divided in the center for 2, 8'x30" sections that can be split into 6, 30"x30" love shacks if needed. I think Im gonna try the commune type set up 1st like Randall uses. I plan on one age group on each side. Then once there all of age, pick my breeders. Hope I'm still on your list for butler eggs in the spring JJ.
