OK so I have 4 white Muscovy ducks that are clearly pure Muscovy but I have 2 black ducks that I bought from CL this fall and was told they were also Muscovy. I'm starting to question that they are true Muscovy though. When I went to get them they were in with their mother who was clearly a Muscovy as she had the caruncles. But these two do not at all show any signs of the caruncles. They are as big as my white Muscovy. They have a beautiful green sheen. So I'm not sure what I have and I'm wondering if they will be fertile. And I'm not even sure if they are boy or girl.....any help would be great. I will get some pictures of them in a little bit to show you guys. Thanks for your help!
