Quail 30 eggs not pipping?

[DAttard]

I've a mix of my own Cortunix eggs, and shipped Celadon.
I candled all prior to lockdown, and all of both varieties had a great rate of viability.
However, I'm on Day 17 and all of my own chicks are into the brooder - I've little activity (3 barely pips) in the Celadon.
ASK ---> At what point/day do I open it up and have a listen, and/or candle again?
I paid ALOT of money to ship these darn eggs and really had my heart set on having a Celadon covey alongside my Cortunix!!
Argh

Incubated 37.5 / Humidity 40-45
Lockdown 37.9 / Humidity 55-60
