so I have a trio of what I'm pretty sure are welsh harlequins (dark bills on the girls), not silver appleyards as I was told when I bought them. ok, they're nice ducks and I'll keep them, just get the silver appleyards in the spring <sigh>. here's my question... what size should WHs be, relative to rouens and cayugas? I've got what I'd consider medium sized rouens and big cayugas, and the WHs are bigger than my medium rouens but not as big as the cayugas. I had read that WHs were medium size ducks and these look to be heavy/large ducks to me. what would be typical size for WHs?
