Hmmmm!

Hillbilly, you already have HOW MANY duckies? Seeing as you are
very fortunate with not having many predators, you are gonna wind up with more ducks than you can shake a stick at.
(Just a figure of speech! Not that you’d ever have a reason to raise a stick to your babies!) You are gonna have to go on a poor man’s diet in order to feed all of them. And obviously male ducks are not as vicious to each other as cock/erels are.
I’m very curious, so realistically speaking, how many could you possibly add in just one year - by natural means of broodies, no incubators?
In your case I believe
duck math is stronger than
chicken math!
