I have 6 six month old ducks. Two Blue Swedish hens, one Welsh Harlequin hen, two Anconas a hen and a drake. I also have an Appleyard drake that I bought as a hen but turned out to be a drake. He is huge. I purchased the ducks as babies and thought that if I got 5 hens and one drake that would be good. Anyway that was not the case, I now have 4 hens and two drakes Since the Appleyard drake is really big should I get two or three more large breed hens for him. I do not want him to fight over the other smaller duck. What is your advice on this matter? What breed?
