I am getting 6 cornish males(2 of each, buff, dark, red laced white) and 2 delaware males. I know the crosses don't need much space because I have read they don't move much. How big would a tractor for mine need to be? In the future I might get some Colored Rangers but not sure I want 25 at a time. Other than that I would order enough from Ideal to reach their $25 limit, or get a few cornish for breeding and do my own. I owuld like to only build one tractor.
