Will eggs get bigger?

last year when my hens started laying the eggs where very small but by spring they where bigger the store bought eggs. they where worth the wait.

 

The eggs I get from my 5 month old pullets (BOs and RIR) are fairly small. Not nearly the size of eggs from the grocery store. I was wondering too if the eggs would get bigger. But I love the eggs just the same!

 

Pullets usually start laying small eggs that will gradually get larger as they keep laying (not counting the occasional odd double egg) and hit full size after a couple of months or so depending on the breed. Some types, like sex-links or White Leghorns bred for egg production will just always lay bigger eggs. After their first molt when they start laying again, those are usually the largest their eggs will be, and they will keep laying about that size until they get old.
