Is it possible to tell sex of ducklings in the tsc bins? I would like a pair or two females. I was thinking I might get 4 pullets and 2 ducks tomorrow. Mallards maybe.I had ducks the first year I got chickens. If I were to get some again, I would gave them in their own coop. Males can seriously hurt a hen if he mounts her. So if you are wanting to free range with chickens I would only get female ducks especially if you only want a pair.
