To Candle or not to Candle, that’s the Question…

During the incubation process, eggs are candled to determine the number of infertile eggs and eggs with dead embryos, together indicated as ‘clears’. This can be done as early as day 5 - 6 of incubation by an individual candling light, but it is time consuming and the risk of candling errors (e.g. accidentally removal

Managing Incubation Temperature to Combat Increased Early Mortality

As a breeder flock ages, the number of ‘clear’ (infertile) eggs increases as a result of decreased fertility and increased early mortality. Consequently, with higher numbers of clear eggs, a higher proportion of the heat produced by developing embryos in the fertile eggs is absorbed by the ‘cold’ clear eggs placed around them. Embryonic temperature

Establishing True Fertility in Hatching Eggs

If it comes to discussions on fertility two different definitions are practiced. A true fertile egg contains a well developed germinal disc (blastoderm), which indicates that the oöcyte, or zygote, was fertilized and an embryo developed during egg formation. Secondly, in the practice of the hatchery fertility is often based on candling, whereby all clear
