@Phill98 summed up the answer very well, and he's right, this breed really does grow on you. It's not uncommon for people to dislike their appearance, especially if they've never raised the birds before, but they really do grow on you. Of all the breeds I've had, including several that are fully feathered, the NNs have become one of my absolute favorites for an abundance of reasons: they're exceptionally healthy and hardy, the have some of the most charming, friendly and amusing personalities I've ever encountered in a chicken, they're quite intelligent, they're prolific layers of large eggs and lay all year round, and if you do in fact keep them as meat birds, they take much less time to process and give you outstanding meat. And after having them for a while, you may find that like me, they stop looking ugly or strange, and then you start imagining what crossing these wonderful birds with other feathered birds will wind up looking like.
