My DH and I where talking about this today and his granddad and grandma kept a farm yard mix and had great egg layers, good foragers, hens that hatched their own eggs and great meat birds. I think sometimes have a few different breeds and mixing them gives you the best of all of them. I have a barn yard mix hen that has given me an egg a day since she started laying. I am going to try this with my flock and see what I get when I hatch some eggs this summer.
