Button quail no pip day 17

[Mayazoid]

It's now day 17, and neither of the button quail eggs I have have pipped. The one is too dark to see through, but the other there is a live chick in, the veins are still there. Should I be concerned about them not starting to hatch yet?
TIA

You're still seeing veins, the chick is not ready to hatch. You'll just have to be patient.

You're on Day 17, how are you counting days?

Shouldn't be much longer.

Did you use a Calibrated thermometer with your incubator?
