This is a great reminder of how important it is to support local farmers and small operations, which increase the resilience of the system as a whole.
That said OP is asserting local costs haven't changed without evidence. Even if that were true (and I don't think it is- local farms are also being hit hard eg duck farming in NY) it probably speaks far more to small operations having a harder time changing their prices. Or the cheap eggs are just places who haven't been hit yet.
A dozen large eggs there right now is $7.90, which is right in line with what their costs have been for at least the last year (they are one of the more expensive local brands).
Unfortunately I just went to the grocery last night, so I don't have any reason to swing by today, but next time I do I'll try to remember to snap a pic of the egg section to share.
I've seen a bunch of posts online from the farms about how they're doing biosafety protocols, keeping groups of chickens isolated from each other, etc. I'm sure that increases their costs somewhat, but whatever they're doing seems to be keeping them insulated from the worst of the flock die offs, and regardless, their prices haven't really changed.
If a small farm gets an infected bird, they can't just raise the prices of their eggs. Those eggs will just disappear from the stores because all the birds are dead. If they are doing rigorous isolation, like hiring totally separate people taking care of completely isolated flocks, that should increase their prices. Farms that are spending more money on isolation and chosing not to increase prices are still at high risk- they just haven't been unlucky yet.
Regardless, we have continued to see the availability of all the usual local eggs with very little fluctuation in price. Perhaps they have all been lucky.
