All of our bantam chicks, game birds, turkeys, and some duck breeds are available as straight-run (random gender) only. This means that the hatchery will simply package your box without checking the gender of those birds first. If you are ordering 50 or more straight-run birds, you are likely to get about a 50/50 ratio on genders, but it is hard to say what that breakdown will look like for smaller orders.
On a lot of our chicken and duck breeds, you can pay a little extra to specify which gender you need or want on your order. Any breed that you see the "Gender Options" field on the breed page with "Straight-run, Female, and Males" available, is a breed that we offer sexing on.
