Perhaps apropos of nothing, but just as a point of clarity, Biden was being blamed for his financial policies causing general and widespread inflation, which included the prices of groceries, a small subset of which was "eggs". Eggs just got caught in the national spotlight because it's an easy marker for which everyone has some knowledge.
This specific "price of eggs" debate about Trump lately is really more about eggs specifically; and no doubt it has at least a little to do with the 20 million chicken holocaust a couple months ago.
