Q. Just wondering how you can tell that an egg is fertile? Does it look different from an unfertilized egg? I was also wondering how many eggs you can hatch in an incubator at one time and how long it takes them to hatch?
A. Regarding fertile eggs, you first need a male – duck or chicken (or purchase fertile eggs online). The next step to determine if an egg is fertile, incubate it for a few days and then candle it to see if cell division has begun. How to Candle Eggs »
