No you do not need a license to sell eggs in California. You do need to put those safe handling stickers on the egg cartons though. The ones about not eating the eggs raw. You can get those from Nasco in Modesto if you are near there, or you can find Nasco on the web. Just find the agricultural catalog. They have a lot of different divisions.
Found this out over the weekend. In CA, you need a license ($500/year) and employ a food inspector. This ranks right up there with shutting down lemonade stands. The weather here is looking worse and worse.
here in Indiana as long as your hens are on the same property as you sell on (like in your backyard and you sell them at your front door or in your garage sale) you have nothing to do but sell, otherwise you have to go through the state egg board, but that varies state to state and comunity to comunity. But for some reason here in Indiana you can't sell raw milk.
