I have a muscovy, 5 months old, who I thought was a boy due to size and hissing. My female has been flying well for about a month. Today, my suspected male took flight - a good long flight. Could this be a girl?
We have one duckling who is developing a lot slower than the rest. I'm sure our brown one is a girl and the other two big boys, but still on the fence with Teeny, the developmentally delayed one (the one with a primarily white chest). Any guesses?
