Hello all-- Next month I will be getting 2 more ducks from my local farm/tractor supply store. I currently have 1 female and 1 male--I am seriously hoping for two more females. But, they aren't sexed at the store-so what you get is what you get. While I have watched countless videos on vent sexing--I'm not sure I feel comfortable standing there in the store violating a few ducks while people watch in awe. Are there any ways to tell gender by their coloring at such a young age? Thanks!
