I currently have four ducks, three hens an a drake. 2 Blue Fawn Rouens, and 2 gray Rouens. 12 weeks oldThey're awesome, but I need to build on my duck flock. I am building a coop probably this fall. I have one already, but since I want up to 20 birds at a time, I am building another. My current coop can house 10-12 birds. I love ducks, and the ones available to me are: Magpie, mixed breeds, Welsh Harlequin(?), Cayuga, Muscovy, and maybe a couple different breeds. I'm looking for 1-2 really good layers (probably Welsh Harlequin) but mainly for 3 really good all purpose ducks. They'll brood and hatch their own batches, be good for eating, and lay eggs, as well as somewhat be pretty. What is best for my situation? I am interested in Muscovy ducks, but the caruncles on the drakes are kind of repulsive if there's a lot, and I don't want to end up with Mule ducks. But I want both genders, in this new breed. If I went with Muscovy, can I only let the hens hatch their eggs, removing everyone else's to prevent mule ducks? And will a Muscovy drake fight with my Blue Fawn drake if there is only 6-ish hens for everyone? The new breed would be introduced as ducklings, to my 12 week old ducks. I might build the coop earlier, too, if it would help with aggression and what not.
