Question: How long between hatching?

[Minniechild]

So after Molls and Goldie's first batch all went to the great lake in the sky, another axie very kindly laid some eggs for me (I'm thinking Bertie). Sadly this spawn (around 50 eggs) has had a very low fertile rate- 6 total have developed to gills, eyes etc. Of the six, one has hatched so far- a little dark copper with quite a bit of spunk three days ago. Considering how long it's been since the first one hatched, I'm worried about the other five- they seem to still be alive and kicking in there, but aren't out and about yet.
Thoughts?

Give them a chance, especially if they're still wiggling. They all should hatch out over a week's time.

Thanks! Just seemed so long between- especially as the last lot (despite the differences in laying times and when they moved into the slightly warmer lounge room) were all out in 48 hours
