Hi from So Cal! Down here, Riverside County, we just keep it on the down low in our community! IMO You need to follow very safe sanitary collection and storage husbandry. Many of us, like you, have a few extra dz/wk. My neighbors don't want store bought eggs. It's nice to be able to "share" and pocket a few dollars to help pay for the feed. There's no clear law for folks selling a few eggs, but many laws that could overlap, as the county needs $$. Some things you might run into. Health Dept, Food handling classes, Food and Ag, Zoning, business/vendors licences... My neighbor had to take her fresh eggs sign down. She needed permits and a plethora of other items once she put that sign up, it opened Pandora's box.
Like @DawnPatrol said, the new law and AI drove the prices way up. I never dreamed folks would be begging to buy my eggs.
With 10 hens, it's not like you would want to rent a booth at a farmers market. We have community FB pages down here to stay connected, find a piano teacher or handyman etc. We have a community FB Buy/Sell/ Trade. Someone will post "does anyone have eggs"? or I have X dz eggs" PM me. There are never enough eggs for the folks that want them. We just go by word of mouth. I only have 15 hens. Wish I had more!
