Depends what you mean.
You can't go wrong with the Broiler crosses, but if you're wanting eggs as well, then you should look up some dual-purpose birds.
Jersey Giants are good meat birds once finished, but it takes awhile to get them there. Australorps, Rocks, Rhode Island Reds and I've "heard" Orpingtons make good meat birds.
I KNOW that Brahma X Australorp crosses are good meat birds...YUMMY!
