HELP!!! Late hatching quail eggs!!

[Maiahr]

I have a question. On day 18 only one quail baby has hatched. It’s been about 12 hours since it hatched and he’s all alone. Should I leave him and wait for the others or place him in a brooder alone?

Did any others hatch?

They can take up to 21 days so just be patient (don't worry - I know how hard that is). There may have been a bit of a temperature dip that set some back, and they will pip internally and wait until they know enough of them are going to hatch at a similar time. If there are no external pips you could take a few out, one at a time, without turning the egg at all (or the chick may get confused and try and turn around) and candle to see if you can see any little shadows in the air cell. Good luck!

If there button quail I've found there typically dead between day 20-22 that's what happened with my first clutch ever died prox between or on day 20-22 so no guarantee after day 20 AT ALL

Temperature does make a difference. I've had naturally incubated ones take up to 22 days to hatch in spring and autumn due to dips in temperature overnight. There's never a guarantee, but there's always hope and I don't believe in discarding what could be perfectly healthy chicks that are just a little late. I also find this with my cockatiels. Naturally incubated eggs are often 'late' but the chicks are still perfectly healthy.

I think I might turn off the fan to increase the temperature (my sister told me it was 100° when the fan was off) and just make it a still air incubator for the last couple of days-or until the eggs hatch (there is some vents/holes so I don't think oxygen will be a problem).

What do you suggest?

84% humidity is very high, too high for quail eggs.... you really want to aim for 65-75% depending on the breed... Did you get any hatchers?
