Just did a little bit of research, and it looks like the market for eggs is extremely localized. Most are laid, processed, packaged, sold, and eaten within a couple hundred miles. Most are a matter of days (2-5) from hen to shelf.
So, when a farm has to purge all of the hens, nearly all of the supply impact is in the local area. Stores can make up for it by trucking them in from a little farther away, but the cost of that rises pretty quickly, and escalated even more if multiple farms get wiped out.
So, as far as eggs go...there really isn't a national market or a national measure. It's local to possibly regional. Kind of explains why Flat and Uber are paying $3-4 a dozen and I'm paying 8. I think 3 farms near me have been purged - one of them a couple of times. You guys have maybe avoided that.
There's also no doubt some profiteering going on, using the news as an excuse to add a bit extra to the price of a dozen
