I have already posted this question but when I came back to the forum to see if anyone replied back to my email that I had sent, it was gone so I am going to post it again :)

Once before someone told me that one way to tell male and female muscovies apart is thatthe males have a curl on their tail...We thought we had a female mallard because she is brown like the females but not completely grown yet. She is only about 5 months old...But..she has the curl on her tail..I have never seen it before on muscovies but she definitely has a little curl. So, is that true for mallards also that their tails curl a little? Do you think she is a male or a female? Thanks Genny
