I'm about to obtain a few magpie ducks including one drake in an attempt to perpetuate the breed and to ensure a continual supply of eggs for eating. My question is that the only way to do this past the second generation is essentially inbreeding. Is this ok with waterfowl? I haven't found any information about this specific topic, so my assumption is that it's ok. I wouldn't do it with other animals, but again, I'm new to ducks. Advice??
