Just before I left for the airport, I heard Sophia squawking in the coop, and when I went to investigate, sure enough she'd just laid an egg!
A going away present? (no, just nice timing)
After placing the egg in the carton, I snapped this picture (to the right) that illustrates just how different-looking the eggs are, even though they're all from the same age (23 weeks) and breed (Barred Plymouth Rock) chicken.
Sophia's eggs are the darker, thinner ones in the top row. ZsuZsu's are the lighter, rounder ones in the bottom row. The egg on the left-most slot in each row is actually the first egg each of them laid for us (I still haven't gotten around to blowing them, yet).
Mind you, these aren't all the eggs they've given us, as we've eaten all but what's in the picture.
We'll keep track of how the eggs change over time, whether it's getting bigger or changing shape and/or color. For now, I'm just amazed that it's so easy to tell which egg came from which chicken!
