how do I know what kind of duck the ducklings are. I go to atwoods and most of the workers don't know mush about the birds they sell. so I will be blind going in there. I been looking at pics of baby ducks a lot of them look alike but are different breeds. should I just pick the ones I like or know the exact breed I need. I would like 3 or 4 babies. I will try the eggs like my chicken eggs but mostly just want the ducks cuz I want them.
