Yes, that's exactly what you think it is: our first egg.
I should clarify. Not ours, exactly, since we didn't lay it. And not an egg from our original flock. But an egg laid at Mucky Boots all the same.
The new flock we got from Ev is about nine weeks older than our existing flock, and a few of them had just started to lay before we brought them home. So yesterday, their first full day at Mucky Boots, they presented us with two beautiful creamy tan eggs. Yes, we ate them, and yes, they were really, really good.
Good chickie chickies!
