This is my first time owning ducks. I have 3 mallards. 1 hen and 2 drakes. They are about 11 weeks old. 3 pekins. 1 hen and 2 drakes. They are about 10 weeks old. Last but not least 5 cayugas. I think 2 hens and 3 drakes. They are about 7 weeks old. I know I have to get rid of most of my drakes. Like probably all but 1. I do however plan on getting some more ducklings in a couple weeks. Will not do a straight run. Will get all females. Anyways, I am expecting they will start mating soon? Is this correct? I watch them and once I start seeing "issues" with my numbers I will be getting rid of some of the drakes. But I do not want to do it before I need to. 1 I like watching them and 2 I want to keep my favorite drake or one that seems to be gentle. They all live together. Free range during they day and locked in the coop at night. Depending on when I get up up the morning they get 12+ hours of free ranging. Each breed stays close together since they were raised together. But they all stay pretty close together as a whole flock. Any advice on when I will probably have to start thinning them out? Any advice on picking which drake to keep?
