Is there an ideal ratio or does it depend on the particular dynamics of the individual ducks in a yard? I have 18 ducks, 3 Khaki Campbell drakes, 13 KC duck hens, and 2 Pekin duck hens. There are 4 separate little houses in the duck pen where they go in their own little groups each night, and they all free-range together throughout the yard during the day. The drakes don't seem to fuss or fight with each other, and each keeps primarily to his own group of duck hens. I have yet to see the KC drakes mating, or even paying much attention to, the Pekins. I thought the ratio might be the same as for chickens, 1:10, and had planned to show & sell one of the KC drakes at our next county fair. But since they're all getting along so well, and since each drake seems to be the head of his own flock of girls, perhaps I should keep them all. Please let me know what you think. Also, do you think it would upset the groupings if I took 1 of the drakes & 2 of the duck hens to the fair just to show, & return to the yard in a few weeks?
