I looked out on the lake to check on my Pekin boys, ( I have two males) and we have a THIRD white duck on the lake! I think it's female (no drake feather). She's smaller than the Pekins with a more slender neck like a mallard, white all over except for black v shape on her booty, and her bill is yellowish orange and looks like it has a little black on the bottow side. (not as bright orange as the pekin's bill) They are swimming around on the other side of the lake so I can't get a good picture right now. I'll try later. Any idea on what kind of duck she might be?? White Mallard maybe?? I wonder where she came from??
