You might be able to check the regulations in your location on-line on the town/county website.
Before I began selling eggs, I checked the SC Dept of Agriculture's regulations which permit selling eggs from a farm stand. I didn't find any quantity listed. I didn't think to check my town's business license regs, though.
I'm inow n the middle of trying to settle a problem over selling eggs in a village in coastal SC - I've been selling eggs for about a year, with a sign on the side of the street and a slit in the garage window where people can put their money.
I've just been told that I am in non-compliance and need a business license and a zoning permit (although raising and selling poultry and poultry products is permitted in the town). I was told that my non-compliance was being ignored until I wanted to put a notice in the town newsletter to let people know the eggs were moving to a stand behind my garage instead of being in a box in the garage window (which gets too hot in the summer).
The business license regulations list "egg production" which I was told applies to selling eggs, not to the chickens - someone else did suggest that it might mean that all women below a certain age need a license. If so, I'm too old, so it won't apply to me.
I've requested to be on the agenda at the next Town Council meeting to discussion the "egg situation."
Until then, I've put up a notice that I can't sell eggs, but that the chickens are accepting donations. People have continued to take the "illegal" eggs and to put their "donations" in the window slit.
I'll remove the sign which says "Fresh Eggs" - I didn't know that wording was not allowed.
I'll also contact the Extension Service Monday - I've tried going on-line to find out if there are state or federal regulations, but I couldn't find any that appeared to apply to my situation.
