I used to breed quail along time ago. I normally had good luck say 70-80 percent hatching out but that was with a GQF still air incubator and turner. The last 3 days you have to stop turning them and increase humidity a little.The breed determines how many days total. I had button,bobwhite and pharaoh quail. I know other types are harder to get to even breed much less get eggs to hatch.
If they make it out you will have to show them how to drink but they will drown themselves if water container is to deep. I used the one that fits a glass jar then you turn it over. I put marbles or rocks so they couldnt fall in.

Good luck hope they all hatch out
