So I saw on the CSRA Hobby Farmer FB page there is a class for candling at the end of March. Is it a difficult class? I've never candled before. I didn't even know I needed to take the class if I was going to sell eggs when my girls start laying. I also think it's a pretty interesting thing to learn. 
Are there other classes/licenses that I need if I sell eggs?
