The first thing to know when you want to hatch eggs is that you need is a male quail and female quail, multiple females, about 4-5 for one male.
Quail start to lay really young, typically 6-8 weeks of age. They are fertile at about seven weeks.
You want to store collected eggs in a cool, dry place, points down just as you do with chicken eggs.
Do not wash your eggs as you collect them for your incubator. Avoid excessively large or small eggs. Large eggs hatch poorly and small eggs produce small chicks.
You want to set your incubator at 100F. Make an X on one side of each egg, and an O on the other side. You want to turn your eggs 3-5 times a day. This is important for the development of chicks.
Quail only take 18 days to hatch, everything with quail is sped up a little. This means you will need to stop turning the eggs are day 15 and make sure that the humidity is up for hatching.
