I hopefully will be purchasing 30+ acres within the next year and am excitedly trying to figure out which chicken breeds would be the best for both Egg laying and Meat production. I definitely do not want to have to constantly be purchasing new chickens for my meat flock. My hope was to have a few breeds that I would be able to put hens in with roosters in order to get my replacement pullets and hens as they age. I love the Golden Comets, ISA Browns and others but they are all cross-breeds and I don't want to have to keep "Parent" Stock. What other breeds would be good for what I am looking for?
