All of our breeds are sold straight run, and customers have a 50/50 chance of receiving males or females. If you are looking for a certain number of female chicks, we'd suggest adding a few extras to your order. We do offer older ages including: juveniles, adults, laying hens, pullets or roosters if you have a specific need. The list of those breeds is found here ... We are happy to arrange a custom order as well. Please contact us.
