If the eggs are over a heat source, be sure the cage floor never exceeds 90F.
Put a lot of moistened sphagnum moss in, to keep the humidity up.

Expect mom to act evil towards you--that's her job. Once you have an incubator, put a hand towel over her head, grab her behind the head and by the tail, and unwind her from the eggs. Move the eggs into the incubator, and wash mom in warm water with a baby soap or a few drops of dish soap in the water. Clean the cage with soap and water. These things remove all of the smell of the eggs, so that mom will snap out of it.

Most females will be back to their old self once they're off the eggs. It's like flipping a light switch.
