The white is Pekín, the mallard looking one is probably a drake Rouen(I have some that just started to get their gray feathers), and honestly I’m not sure for the black spotted one. I have never heard of a Cayuga turning white, and it doesn’t have the sheen-

️they actually do turn white so disregard this sry so it might be a Cayuga-

️ I don’t think Ancona becaus they are usually mostly white. Maybe a mix of something? Blue Swedish are more gray than black and have defined chests. Yours is probably a mix of something.
This photo is of a blue Swedish, so I don’t think your is. And he doesn’t really stand like a runner so probably not one.
