The reason you get more males then females with straight run in hatcherys, is because they usually sex out extra females, and just throw you whatever they have left. Which are usually males. But if they don't sex ANY of their birds, then you will get a 50\50. Good luck!
X 2 I would not buy SR if the hatchery sexed because most people want females so you end up with boys. No saying for sure what you'd get with luck of the draw but that would help your chances. I am not that familiar with bantam ducks but I know most hatcheries don't sex bantam chicks because of their size. You may end up having to get unsexed. But as previously stated, have a plan for excess drakes.
