A question about the size of eggs

[Jenise]

What determines the size of eggs? I always presumed it was breed, but I picked up eggs from a local guy I hadn't bought from before, and the eggs were the tiniest chicken eggs I've ever seen--some green, some brown. More or less the same colors I see around here, but uniformly, they were smaller.

I think there are breed differences, but if I recall correctly, the big issue is the age of the hen. Older birds lay bigger eggs, as a generalization. I don't know enough about chickens to know why this is.

"While you cannot alter the basic pattern of how egg size changes as hens age, the feeding and management of your hens can have a measurable impact."

Gosh, just like us human chicks.
