GG CANDLING
Bad breeding results are frustrating and may be caused by several different factors. The most
common causes are illustrated below.
Gather for this purpose as much information as you can about the incubation in order to be
able to analyze the problem thoroughly. Register all relevant information regarding the placing
of the eggs, de incubator settings, the hatching dates, the weight losses, the number of
younglings and their condition.
After 8-10 days from the start of the incubation period it is advisable to candle the eggs in
order to be able to remove the unfertilized eggs. Candling should be done preferably in a dark
room. You can get good candling lamps at your supplier’s.

) Clear when candled - probably infertile (or very early death)
when candled at 8 days
2) Fertile with red blood vessels - after 8 days
3) Red or black staining - early death when candled at 8 days
4) Embryo with red blood ‘ring’ - early death when candled at 8 days
5) Dark outline with ill defined detail - late death (10-16 days)
6) Live embryo with bill in air sack - due to hatch in 24-48 hours
