That's more than half of the eggs in our incubator that have hatched so far! We haven't lost a chick yet either, though we have one little guy who is struggling, so we're keeping our fingers crossed.
Four more in the incubator have substantial pipping. I hope that they bust out of there soon!
Meanwhile, the smell coming off of the incubator is gnarly. It's not a rotten egg smell, per se, but it's still pretty nasty. Please hatch, bambinos, so Mama can clean that thing and put it away. :P
