Question: Eggs on day 23 still haven't hatched

[Boggles]

Hello
This is my first time at hatching eggs I am currently on day 23 And the temperature is about 16° there eyes have formed and I can see you gills. I would like to know how long it will be until they hatch. Any help is appreciated
Thanks

I've got a more accurate tray of water temperature and it varies from 12-15.

At temps that low it could be up to 28-30 days. Doesn't look far off though.

Thank you for responding. One egg hatched yesterday morning which it's the cutest and placed some daphnia in their morning.. The others have not hatched yet. Is this normal for one to hatched and then 12 hrs later the others still haven't hatched? I thought when one hatches the others follow within 12-24 hours. When should I expect the the others to hatch?

Mine hatched over a span of three or four days -- I don't think it's that unusual. Just keep an eye on them.
