I lurk on this forum alot and don't post much, mostly because if I look hard enough I can find answers to just about anything pretty quick! This is such a great site. Anyways, I'm not sure i can find answers to this. My brother has acquired three Muscovies, a drake and two nice ladies. He loves them, has a nice sized pond for them, and they seem really happy. We call them The Fonz, Laverne and Shirley. My brother also has somewhere short of 50 mixed chickens, all free ranged on about 1/4 of an acre, and the ducks fit right in, sleep with the chickens in their coop, and have recently started laying a couple eggs in one of the chickens nest boxes. They've also laid a couple elsewhere. My brother is now getting the bug to incubate some of their eggs, and was talking about raising them to increase his flock of ducks. My concern was whether inbreeding between parents and kids could be a problem once the ducklings are mature. I've heard it's not really a problem with poultry like it is with mammals, but I'm always concerned about those sorts of things. I also mentioned to him about letting the ducks sit on their own eggs if they're willing. Has anyone ever let their Muscovies brood their own if they seem to want to? None of us have bred ducks before, so we're total noobs on this. He had runner ducks for awhile and they were pretty aggressive to his chickens, but he couldn't tell the sexes of them, so there may have been too many drakes. These three are absolute sweethearts!
