Incubating an egg is not easy. You need to have the right temperature for the right amount of time, the right amount of humidity and a good, strong flashlight for 'candling' eggs, and even then, you never know how many of the eggs are going to hatch. It will, of course, depend on how many eggs have been fertilised. Discovering what's going on inside those shells can be a real challenge.

Things you need
- Bright flashlight
Hold the egg carefully between thumb and forefinger over a flashlight, candle or bare light bulb. Do this about three or four days after the start of incubation.
A fertilised egg will appear to have small spiderweb type veins inside the shell when it is 'candled'. An unfertilised egg will appear clear and should be removed immediately from the incubator.
Candle the eggs every third or fourth day to find out if the fertilised eggs are still viable. If they are, the spiderweb veining should have grown considerably larger and there should be a solid mass within the egg.
Candling will also reveal the eggs that are no longer viable, for whatever reason, by showing a dark mass that tends to slosh around in the shell when shaken gently.
Smell the eggs periodically. Viable eggs will smell OK but the rotting ones will naturally smell bad right through the shell. Dispose of any smelly eggs as these will eventually contaminate the rest of the eggs if allowed to remain.
How to Tell if an Egg is Going to Hatch
Tips and warnings
- Only put as many eggs in the incubator as it can hold at one time. Overloading is detrimental to hatching.
- If your incubator involves a bare light bulb as the heat source, be careful when putting your hand in there to check or turn the eggs. Severe burns can be incurred by accidentally touching the bulb.
