I would like to blame it on the signs you have hanging in your windows, but unfortunately, I cannot even blame your plight on America's abject failure to MEGA correctly... which is an acronym for "Make Eggs Great Again".
Where the egg problem actually lies is in the food supply itself that is fed to chickens which are called 'layers' in the industry, which are those chickens not destined from their humble beginnings at the 'hatchery' to form a key ingredient at a Kentucky Fried Chicken outlet.
Chickens which are 'free-range' birds or those who are kept in captivity 24/7 but are fed organic feed, are the ones who produce eggs which have a very high calcium content to their egg shells, thus producing near bullet-proof eggs which are found to be much more suitable to the US marketplace in particular considering 2nd Amendment Rights and all.
However, organic eggs are very expensive to produce because the organic feed is not cheap, nor is the daily egg production rate very high for a typical 'organic' egg-laying hen. 🐔
Enter the age of force-fed chickens who never see the light of day, who's environment is that of bright lights being left on 24/7, who's feed supply is imported to the USA from China which contains animal renderings from slaughter houses along with everything else except calcium, but who yield double and sometimes triple the daily egg production of that of an organic-fed hen, but who's egg shells are paper-thin as a result of their Chinese feed and who's egg yolks are a pale, pastel yellow color as a result of their Chinese feed and barely have the taste of an egg when eaten in any culinary venue because of their Chinese feed.
The same thing goes with fresh salmon one can purchase in an American fish market. Those salmon seen as whole fish in the display case in a fish market, are raised in salt water fish farms located in China and are flown-into the USA daily on FedEx.
Those salmon however, are fed pelletized food made from animal renderings as well which yields 10 times more grease (and yellow grease at that) than a wild salmon is capable of producing, considering that a wild salmon doesn't typically produce grease at all. It produces a clear salmon oil naturally, but a salmon does not naturally produce a yellow grease substance if it swims in the wilds of the ocean.
Only 2% of all salmon consumed in the USA each day are caught in the ocean by American fishermen. Those particular fish don't travel very far to find a domestic fish market on either the east or west coast of the USA, which is why 98% of all salmon found inland and thus consumed within the interior of America is flown-in from China each night.
I see it in eggs, I see it in salmon and I also see it in dairy milk.
The reason your eggs are delivered cracked or broken from Walmart has little to do with Walmart or it's egg handling protocol, or their delivery guy's driving habits unfortunately.
