How to Use a Candler
To candle an egg, place the candler against the large end of the egg, where the air cell is. The light will show through into the contents of the egg, and illuminate the embryo within.
Embryo Development
Eggs develop rapidly once the incubation process begins. In the first 24 hours after starting, the weight of the embryo is .0002 grams (based on data from an average heavy-breed chicken). The eye begins to develop even at this stage of growth. At 25 hours, heart tissue begins to form, and by 42 hours, that tissue begins to beat.
When to Candle

How to candle eggs
After a week of incubation, place your egg onto your egg candler in a darkened room and turn on the light. You should be able to see shadows from inside the egg. With practice, you will identify fertile eggs by the dark dot, the embryo and the spider-like blood veins spreading out around the egg.
