I miss the old two, or even more on rare occasions, yolks in Jumbo sized eggs, but at that I think the Jumbos you buy now are often just big enough to be sized that way.
Years back you would open a cardboard egg carton and you could see some were big enough they were a tight fit.
In a few, very few, grocery stores, years back, there used to be super jumbo egg cartons.
My cousin's chicken are a mix of varieties for the sake of variety, and lay the so called easter egg colored eggs also, farm chicken do have shells a lot harder to crack and the yolks are a much deeper yellow actually closer to orange.
Because I am of the curious type, I did buy , back when egg prices were normal, some those supposedly best ever eggs, with their logo on each egg shell.
I think they think aesthetics sells eggs, but it was different to open the carton and see their perfectly aligned 12 eggs, each with a logo.
