I was wondering how I could provide evidence for you other than walking to the grocery and taking a picture, but I found at least one of our local farms that has their prices online:
https://www.maplewindfarm.com/collections/retail-store -- I'd expect it would be quite easy for them to change their prices on their own storefront and in their farmstand, where I often buy their eggs.
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.
