After switching them to sphagnum moss (and having one that separated and turn to jelly), the eggs hatched! It took 52 days for the first to pip, and by day 54, all thirteen were out. None have any kinks. All are deep in shed.

The frustrating part is . . . no ghosts! I started with the grandparents seven years ago (a hypo male and anery female). Just like last year, I got anerys and hypos, but no ghost. Here's a picture of one that I'm hoping is a ghost, but I can see enough color to make me think hypo. And a pic of the clutch. markg, thanks for your input!
