Cayuga Drake?

[Stipenvlerk]

That's pretty much exactly what my guy looks like in the sunshine on his back, some blue and green (almost what looks like some purples as well) on his back but not nearly as much color as your Cayuga. Since you said yours is 7 weeks old that would put them both around the same age. Since yours is undoudebtly full Cayuga that puts a ton of my doubts about him to rest. Your duck is incredibly gorgeous so thanks for sharing!

Thank you so much!
