When we got our first group of Plymouth Barred Rock hens, they started laying eggs at just under 6 months (23 weeks, I think), and once they started laying, they were regular-sized eggs with your occasional jumbo double-yolker. Our newest group of PBRs (incubated and hatched from the first group) turned 19 weeks today, and for the last 3-4 days, we've been getting a few tiny (about 2 inches from end-to-end) eggs each day, which we are certain are from the young ones. I know it's possible, but unusual, for BRs to lay eggs at 19 weeks, but it just surprised us since their moms didn't. But is it normal for early-layers to start off with teeny eggs? They're pretty comically small compared to their moms' eggs, and I just want to make sure there's nothing wrong with them. They're all eating the same organic feed and free-ranging all day, so there's no other difference I can think of.
