The questions you asked were more than reasonable, hatch date and weight should be as simple as looking down at a notepad and copying a few numbers into an email. I would call or email one more time asking for those details and if he still doesn't address them, maybe take your business elsewhere. If a breeder isn't willing to communicate with their customers on such simple things, I don't know if I'd trust them with more important details like feeding, health, and genetics :/
