I am brand new here. I hatch out various breeds of ducks turkeys ect. I want to start a small time hatchery with maybe twenty breeds eventually. However I want to be able to sex day old chicks, because I plan to ship within the continental 48 states. I have read books and online about the subject . But have not been able to find any real information about it. Most articles just say wait until they are 6 weeks and then you can tell. I already can do that and want to learn how to sex day olds. Does any one know where they teach classes on that subject? I may have to try and find a chick sexer from a hatchery who will teach me how. I am in Braymer Missouri. We have a dairy so going far away is not very practical. Any help would be greatly appreciated!! Thank you very much.
