I've never thought I'd have NN either, thought they were ugly, I think their pretty cool looking now that I have them. One of the best dual purpose, grow at a good rate, less protein going to feathers, easier to pluck, half or less feathers. You don't notice it unless you look the feathers cover up the bare patches, half the breast, half fhe legs, the vent area, all bare, and they have no 'hair' to deal with when processing. Thin skin that roasts up nice, the French consider them the best tasting chicken in the world.
They're supposed to lay pretty good also, mine haven't started yet, but did grill up a couple and they we're pretty good, along with a bear loin roast
