Answers:
Some species of quail won't incubate their own eggs. I'm not sure if that's the case with your eggs (Japanese quail and painted quail are REALLY bad for that!), but you can make your own simple incubator. You'll need a plastic container such as a large ice cream pail, a lamp with a 60 watt bulb and a small container of water such as a tuna can filled with water and a sponge. You'll also want a layer or two of paper towel to give them a soft spot to sit. The eggs will need to be turned 2-5 times a day. and at absolute minimum, twice a day so the embryo doesn't stick to the insides of the shell. The babies will start hatching in a few weeks. Most start hatching at 17 days, but pipping can start as late as 19 days.

Babies are able to run around and eat adult food when they hatch. You'll need to put rocks in a small bowl that the babies can drink from. The rocks will prevent them from drowning. Sometimes you have to point them in the direction of their food and poke their beak into it before they realize it's edible.

That's about it. Good luck!

Read a book called Robert the Quail. The humans hatched him under a lamp. The eggs need to be turned often. Others will know more here.

What happened to the mother? Mother knows best.

You need to incubate them at 99.5 degrees F at all times and turn them at least 3 times if you want them to hatch. You will need a thermometer.

You can use a light bulb,
keep the eggs at 100*,
if the heat is too high,
or too low they will die.
The humidity needs to be
at 60% or the eggs will
not hatch. You can use a
small bowl of water, near
the heat source. It takes
16-18 days, then reduce the
temp to 70-80, when they
have hatched. Prepare a
warm dry place, with a
shallow water source, and
plenty of chick starter. The
area will need to be kept
very clean, or the chicks, will
eat their own manure and die.
The eggs were best left alone.
