Young chickens lay smaller eggs to begin with. And as they get older too.
My LH lays a Xlg egg. And yes they have a small build. She’s now going on 4yrs. Her eggs have dropped a bit in size. She still lays 6 eggs a week.
All things considered I think she’s doing great. Give your young ones a chance to practice laying eggs ... that’s what they’re doing.![]()
I have had the same experience with mine. XL eggs eventually. They started out on the smaller size. Small hens that lay large eggs. That’s the leghorn.

They are nice girls and becoming very friendly with me (smart chickens, they know where the food comes from!) so I shouldn't complain.
