I’m new to owning ducks and I’m trying to verify that I got 3 hens. One is khaki campbell the other 2 are a mix of khaki campbell and domestic mallard. They are 7 weeks 3 days old. I think they have all quacked at least once but I’m not sure since I’ve never had ducks before. They are mostly still peeping though so I’m starting to worry they could all be drakes.
