I do like a combination of a legit website (can have "projects" page, husbandry info, etc.) and then a FB business page for current updates on litters / clutches or available animals. I've seen many breeders have a website and then link their FB business page to it for updates and I like that method a lot. That allows people to find you on Google or other searches for general info about your business and animals and then use FB as a tool to keep people updated on what you have available.
