The transfer of eggs from setter trays to hatcher baskets is routine in the hatchery, while the embryo continues to develop. In the final days of incubation, the embryo prepares for hatching and while embryonic growth slows down at this stage, the maturation of most of the organs continues. The embryo turns its body along
Eggs are incubated in setter trays for most of the incubation period. Three days before hatch, the eggs are transferred to hatcher baskets. In the setter trays the eggs are placed vertically with the air cell (large end) up, while the eggs lie horizontally during hatching. In normal development, the embryo begins to turn to
Breeder farms are often situated away from the hatchery. The distance between the two sites therefore becomes an important consideration when planning the transfer of eggs to the hatchery. Typically, deliveries vary from daily to not less than twice weekly, as increased storage time has a negative impact on hatchability and chick quality. Egg transport
THE STRUCTURE OF THE EGG To be well informed of the factors influencing the quality of the egg (both hatching egg and consumer egg) and those of the incubation and hatching process it is necessary to know the structure of the egg. Below you will find a rough enumeration of the most important parts.
