The most critical factor for setting up a Hatchery is Hatchery Room itself. The following points should be considered for setting up a Hatchery Room: 1. It should be airy and well ventilated. In winter and at cold places it is not essential to have an airy room. Room temperatures from 70o F – 80o F should be maintained. Similarly sunspots on the Machine should be avoided during summer Season by using curtains on windows.
2. Place your incubator near a gas heater where carbon dioxide concentration in the air might be high and kill your embryo.
3. Keep visitors out of the hatchery room as much as possible to avoid the possibility of introducing disease.

Eggs should be picked up daily and stored in egg flats with the small ends down. The Flats should be tilted twice a day. On very hot days the hatching egg may be kept in the kitchen refrigerator in a plastic bag. Sprinkle the eggs with a little water and seal the bag. This will preserve humidity. Make sure that the eggs are placed far away from the freezer section so that the eggs do not freeze. Let your eggs stay at room temperature for a least twelve hours before setting in your Incubator (20-degree F). Eggs should be stored in a separate place than the hatchery room.

Eggs should be set after careful handling. In ‘DAYAL’ incubators it normally takes 3 minutes for setting eggs in an incubation tray. No packing of any sort is needed. Eggs of any size can be accommodated properly in the special tray provided. While placing eggs in the incubation trays the pointed/small end of the eggs should be down wards. Place trays in the incubators, pushing them back until these the rear of ranks. The turning of the eggs is completely automatic and does not require any handling. All the incubation eggs should be put in the incubators according to serial numbers marked on the eggs at their appropriate place.

The washing of hatching eggs is not recommended although many producers think that visual cleanliness will increase their chances of incubation success. It is more important to stress providing good nesting facilities and frequent egg collection to reduce egg contamination. Cleaning of eggs will then become unnecessary. The reason that washing is harmful is that washing aide’s bacteria to penetrate the egg shell through the small egg shell pores. The egg has many natural defenses to prevent the bacteria from moving through the shell. Washing removes the egg shell's natural defenses against bacterial entry, and water provides an environment that allows the organisms to literally swim through the shell pores. When this occurs, the egg is overwhelmed by more bacteria than it can destroy and egg contamination results. Several washing aids and antibiotics have been tested to destroy the bacteria but have not consistently improved egg hatchability. If dirty eggs must be used for hatching, it is recommended that they be incubated in an incubator separate from the clean eggs. This will prevent contamination of clean eggs and chicken if the dirty eggs explode and during hatching.
