Anyone have a comparison picture of a GC versus RIR egg?

My RIR and golden comet are only 2 weeks different in age (25 and 23 weeks) so I suspect either or both of them are starting to lay. We got 1 egg yesterday and 2 today. The 2 today are different sizes with one matching yesterday's egg being kind of small. Both are a nice warm brown.

We figured out today that the GC's egg is bigger at the moment than the RIR's. Today the RIR didn't lay anything and I caught the GC in the nest box.
