I think the Dark Cornish make the best all-around birds that can forage for themselves and grow quite fast for meat. They are great egg layers, with large brown eggs. They are somewhat broody, not very pretty to look at though. They have dense, compact feathers on a muscular body. Mine came from Murray McMurry. Next, not as good at laying but pretty and grow very large and fast are the Cuckoo Marans, also easy to sex early on; as well as the Wheaten Marans, Great birds and my personal favorite for growing out, they have the BEST eggs, great looks, fast growth and are very broody, easy to tell apart very early on as well. They are just so pretty to look at too. Can't go wrong with Marans, but Cornish are cheaper and a great free-range bird.
