Hello! I have 4 muscovy ducklings that i'm raising away from the other ducks right now since they're so young. I was wondering if, when they grow up, and I put them back out with the hen that layed the eggs will the males try and breed with her or the hens breed with the dad? If so is it ok even though they're the mom and dad? So basically if the hens offspring breed with her or the drake will the eggs be infertile or have something wrong with the ducklings due to inbreeding? Do I need to keep them separate?
