Ok, I will put this as clear as possible, though it may sound confusing! hahah. Anyways, it won't be for a while until I incubate some duck eggs, but I was wondering about something. As some of you probably know, I am getting a pair (male and female) of mini silver apps. next week. So, now lets jump ahead a bit, to where I am incubating eggs that came from these two ducks. Ok, now lets say that only 3 eggs hatched which are female, and not male. Once these females grow up, I would like to put them with their mom and dad. But my question is, if the dad breeds with his daughters, but I never use the eggs for hatching purposes, will that be ok? I will probably just keep the original two (dad and mom) for hatching eggs until I bring in some new blood lines ...... Thank you!
