Is there anything I need to know about raising goats?

After walking through the goat pens at the fair, we decided our retirement plan should definitely involve raising goats and making Feta and Chevre.

Question by Coraline: Is there anything I need to know about raising goats?
I want to raise some friendly type of milk goat (which type would be best?) and pygmy goats. Is there anything I need to know, like a specific way to milk a goat, any specific fencing material/ height for keeping the goats in, what they eat. You get my point.
