That sounds like the trip we took to get these eggs. We were on the road all day. From 7:30 AM to 10:30 PM.
I didn't sleep... left around 2am and got back around 5 or 6, I think? We made a couple stops on the way and got stuck a couple times in s****y traffic...
I know, it's so frustrating to know he was growing so well til he got stuck. I still have no clue why it happened.
Embryo stuck on inside of shell while developing is sign of not being turned after collecting until it is set... the longer they sit, the better the chance of sticking to the shell...
