I'm new to having ducks. I have 8 Muscovy ducklings that are 4 weeks old now. I am breeding them for meat and I have the chance to get some more ducklings which are about a week older then these. The reason I want to get some more is because of possible inbreeding problems. These 8 ducklings are siblings. So I was thinking I should get a male duckling from a different flock to mate with my females. Are there usually problems when you try to introduce new ducklings at this age? I used to live on a pond where I saw sibling Muscovies mate with each other. I didn't get to see if they were successful in raising babies. Has anyone experienced whether siblings have mated and rasied a normal amount of babies successfully?
