I only do LF NN, it's really hard to find a NN breeder in all of US let alone the Northeast cause people think there're ugly and not in high demand.
You can buy adult bantams white or red from Duane Urch who can ship adults he's got good quality birds (probably cost a lot though for shipping). I am going to do red LF NN show/breeder sometimes in the fall. I know this doesn't help your search but I tried.
