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.
The "generic egg" have gone from $0.25 a dozen during some price war 6-7 years ago to $6.99. That price has caused the local eggs to sell out first where they used to always be available.
I suspect that the combination of our and other anecdotes in the thread may suggest though that there is some merit to the hypothesis that small, local farms are more resilient to this kind of mass pandemic, although it may vary from region to region, especially with the number and quality of local farms, which is probably much higher where I live than some other rural states and/or in major metropolitan areas.
