I think if you got Cayugas it was probably because you loved them for their many wonderful qualities - stick with your instincts.
I searched high & low for my Anconas and haven't regretted it for a minute. If you research enough about housing and care you'll be fine.
I think the Cayugas and Anconas are similar - not too noisy, good dual purpose, good foragers, and lovely to watch.
Ducks are just the neatest animals, in general, and you can't go wrong.
