Glad to see this - I'm also wondering. 2 Black Stars, 2 Red Stars, 2 Leghorns, & 1 Buff Orp. They started laying in late August, & while getting larger, still seem smaller than store-bought. Except for 1 of the Leghorns who lays a double yolker at least once a week.
Will they keep getting larger, or is this normal size for non-commercial birds? They lay pretty much every day, so I don't think there's a health/nutrition issue.
I only care because I bake a lot & egg size does make a difference in some recipes.
