Day 24: movement, no pips

[SlikerFarm]

This batch of eggs is driving me crazy! We are now starting on Day 24. Out of 8 eggs, two piped Day 21: one hatched, one died after piping. Last night another big pip: died after piping. I just candled the last 5 eggs - ONE has internally piped, and the other 4 are moving, but no pips! I am at a loss! Any suggestions?

This is so far the only chick to hatch out. And she's doing great!
