I breed Cayugas (nowhere near you) and am a member of the British Waterfowl Association who have just asked all breeders to contact them so they can get an up-to-date breed list. So maybe give them a call and see whether they've got anybody close to you. I've got a breeder list somewhere but can't think what I've done with it and it's probably not as comprehensive as calling them. Or drive! I've done overnight trips for birds I wanted....
