Large egg small yolk?

[m00res]

I have a RIR that lays pretty large eggs but the yolks seem small in comparison to store bought eggs of the same size. I was wondering if diet has anything to do with the size of the yolk or if it is just a breed thing. Just curious... Thanks!

Good question - I have no answer. But I'll bump ya up so maybe someone who knows these things will come around...

How old is the hen?

She's a rescue so I don't actually know. I would guess around 3ish. Thanks!

I have no idea why the yokes are small. I have RIR's and the yokes are all equal to store bought eggs. Maybe if they are 3ish their body chemistry is changing and they are just developing eggs with smaller yokes. Mine are about 2ish.
