Actually....that is exactly what he said. The darker ones like you have pictured were khaki Campbells. The yellow were Peking and the others I don't even remember now what he said. Oh, yeah...I think he said there were a few mallards in the bin because someone standing there said immediately, "they fly away" LOL It was interesting to listen to the conversation but I quickly figured out that he was the only one who really had a clue.
Thanks for the heads up! I think I keep staring at too many duckling pics because I want them so badly and they all start to run together. LOL
