Avian Production Management

SETTING OF EGGS

• It is general practice to set eggs at broad end up in incubator which is called as up-right position.
• Setting of egg in up-right position will hold the air cell in a regular position and controls malposition of embryos. This also facilitates development of the head of embryo towards air-cell due to which it is easy for the developing chick to penetrate through the air-cell for commencing of pulmonary respiration. It has been observed that reverse setting results in lowered hatchability by about 8 percent and the quality of chicks are also impaired.
