VeryI'm still not exactly sure what you are asking? who is telling you to kill them and why are they saying that? This sounds like it may be a difference of opinion between you and family members who have different goals. When families have this type of disagreements it can get rough. But all that is your business and for you to manage. Good luck!
What are your goals? Why do you have ducks to start with? Lots of people keep them for things other than meat. I think you need to manage them in a way to keep the numbers where you can properly manage them, you do have responsibilities when you own animals, whether that is ducks, dogs, or cattle. For you that might mean don;t let any more hatch of or find a way to get rid of them.
One of my main goals is to raise chickens for meat. They would never have hatched and lived to start with if I were not planning on eating them. I try to raise them the best I can. Some I hatch in an incubator or buy from a hatchery and raise in a brooder. These are usually out scratching in dirt, eating grass and other vegetation, and chasing insects by 5 to 8 weeks of age. About half are raised by broody hens with the flock. I think mine get to live like chickens in a flock and have a pretty good life up to the point they have a very bad moment. I try to make that bad moment as quick as I can.
I don't feel good when I kill the chicken though the rest or the butchering isn't bad. I try to use as much of the chicken as I can so nothing is wasted. When I butcher I have two buckets. One bucket gets the stuff that I will bury in the garden or orchard to rot and be used by the plants. The other bucket gets stuff that will be fed back to the chickens. That upsets some people but the chickens enjoy it and it gets used. I cut off traditional parts of the carcass for the table. I feed the liver to the dogs. I keep the wings, back, neck, gizzard, heart, and feet to use in broth. I save the bones from the parts I eat directly for broth. I pick the meat out of the stuff I cook up as broth to use as cooked meat. The only thing that goes to the landfill is the bones after they have been used to make broth.
I don't feel good when I do the actual killing but I don't feel bad either. I'm going to be eating chicken anyway, even if I have to buy it from the store. I can buy it cheaper from the store than I can raise it and it would take a lot less work. But it is worth it to me to raise them myself, know where the meat comes from, and treat them the best I can and still meet my goals.
