Yes! Lots of chicken stock....OK not to burst your bubble but most of those breeds will only be available as straight run as chicks. The only place you will get reliable sexing is a hatchery ( and even that's gone down hill) and most of those breeds won't be available from a hatchery.
Last I checked vent sexers get six figures so only big hatcheries employ them. If you want those breeds you are going to have to find breeders who are selling older birds ( not cheap) deal with roosters or get very very lucky. All those things are possible but not all probabl.
