Hi Nicole
Thank you for your response.
I am from Zambia. I'm guessing my ducks are a type of Mallard as that's what they look like from Google? The mum is actually a white pekin and the father is the Mallard looking one. I can tell the sound difference between the adults but not so much with the ducklings yet.
I'm also not keen on eating or selling as they have become our pets. Thanks for info and suggestions. I'll see about maybe giving them away as pets.
Many thanks
