We were out most of the day yesterday, and it wasn't until just before dinner I went down to check the girls' water and food levels. Being an optimist, I just had to look in the nesting box, hoping against hope.
Despite having set diminished expectations on when we'd see our second egg out of Sophia, I was pleasantly surprised to open the Eglu's nesting box door and see another egg perched in the bedding materials!
This second egg (picture to come) is a lot smoother than egg #1, but it's the same size as the first. An informal survey of everyone I've bragged to about our first egg says we should blow out the first egg and save it for posterity's sake as a reminder of the first day of production in our nascent chicken farming history (kinda like framing the first dollar bill taken in at a new store).
I'm thinking that's a good idea.
