They are hatching. They didn't start hatching until day 22 and it is just one chick at a time. I think my biggest problem was the long drive home. They were slow developing and developed at a uneven rate. 48 eggs went down to 24 at 10 days. Out of those I don't expect all of them to hatch. Day 23 is half over and I've still got pips in eggs.
Even with such a high loss, I think I'd do it again. I'd have to do it in better driving weather and when I knew we were coming straight home. I'll add pictures to this when I take some.
Maybe for your drive next time put them in a cooler with chill packs? I've had good success with that when my shipped eggs were delivered over the span of a week. All eggs hatched within 24 hours.
Please do post pics of your fuzzy souvenirs!
