Has anyone ever had quail eggs hatch on day 24 before?

I naively thought I could put Quail eggs under my clucky chook last year. So I did, and unfortunately the hen didn't realise what was going on and stood on the first chicks that hatched killing them. I left the eggs where they were while I went in search of an incubator but couldn't get one right away , and the hen abandoned them. I lost track of how many days she had been on them.
When she had left them for 24 hrs I realised they had probably died and put them outside on a dish to bury later while I cleaned up. I forgot about the eggs and went back in the afternoon to deal with them , the sun was on them and the quail had started hatching. I bought an incubator and used it to set up a brooder box. Those four Quail grew to be strong and healthy.

Sounds about right! Quail are tough little buggers, and that includes they're eggs as well.
