The key factor that nearly everyone misses or perhaps, deliberately ignores, is that chicken eggs are worth their weight in gold to pharmaceutical manufacturers. There's a significant number of pathogens, er I mean, vaccines, that are tested and/or cultured only inside of eggs, and for the seasonal flu vaccines, those pathogen factories are unfathomably gigantic in scale. So essentially, any drain on the supply of chicken eggs for the consumer market may be attributed to the overwhelming and ever-increasing demand from the pharmaceutical industry to use up these eggs so that they can grow viruses, bacteria, and other nasties to, er, checks notes inoculate the population and keep the world safe for democracy. That's the ticket.
