I want to breed several pure breeds, but I like my chickens to live together. What about letting the hens have the main run of the pasture, and having several roosters live in another run, then only putting the proper hens and roosters together every couple of weeks for a day or so? I don't have enough pens to keep each breed separate all the time. Plus, I like to hang out with the main flock all together. And it just plain looks pretty to see several different color chickens all foraging together... it make me happy. Will the roosters fight if they are penned together without hens, but with hens within sight across the fence? Thanks!
