I suspect at the rate California is hemorraging other businesses, it won't be long before the rest of the egg producers either leave the state or are forced out of business as a result of this ridiculous law ... and that's the way it should be. When a state makes it intolerable to do business and compete, they'll have only themselves to blame when business' leave and they lose their tax base.
Two states leading that trend are California and Illinois. Both blue states. No surprise there.
Actually I think this will affect the cost of eggs only in CA.
Most producers will not comply and will maintain lucrative contracts elsewhere.
Then there will be some who comply from out of state and they'll have a lucrative market within CA.
And the going rate for eggs will be $2.50/doz everywhere but CA where it will be $4.00.
Or thereabouts.
