I have a few questions about mixing colors, hopefully someone can answer them. 1. I have 1 black Swedish female and then a whole bunch of blue Swedish (no idea on gender yet) if I mix them all in a breeding pen next year, what color will be produced? Will it be considered a mutt? 2. I have fawn and white runners, black, brown and blue runners, will the fawn and white runners being in the same pen produce odd colorations? 3. Does anyone know where I can find the standards for show ducks? I need to know what I am looking for with my breeding stock, but have no clue as of right now. 4. Several of the ducks I have are crested, is this a trait I want to pass on, or is it considered a mutation? 5. How do you tell the difference between a mallard duckling and a rouen duckling? Ideal has both and I got an assorted lot, no idea which they are! Thanks!
