I have both a Blue and Black Swedish and they are Soooo opposite in their beauty. The blue is soft and shows lots of texture through the various shades of blue with small streaks of black. The black is almost enameled with a high luster and the beetle green/blue/purple iridescence. I am sure they have MANY different lines at Metzer, but our Black Swedish out shines our Cayuga with the beetle colors. I am not sure if that is because the Swedish is so spectacular or the Cayuga is relatively plain. So that is a hard choice.
And you have picked so many different birds, you should select your runners. (I can't believe looking at this list that you need to save the 56 cents per duck - or 31 cents if you choose a Fawn & White to not pick your own colors) I don't see any brown ducks in your group - a Chocolate runner is really pretty. They start a deep brown chocolate color when their feathers are new and they slowly fade into a slightly orange-tan then when you are sick of that, they molt back to the deep brown. Plus in the assortment, you might get two the same color which would defeat the whole point of flock diversity.
Gender: girls for everything you aren't breeding, then if you are breeding (calls I am guessing), the minimum number of drakes that will get it done (that of course would depend on your colors and what you want to breed together.)
The appleyards look like WHs with orange bills, legs and feet (oops sorry Julie, I meant webs)
