It should be noted that the health status of the breeding flock is very important for the production of high quality hatchery eggs. Also important in this regard is the mating ratio which is usually 6-7 males to 100 females for the commercial egg production breeder and 7-9 males per 100 females for broiler breeders. The most decisive factor toward achieving optimum results is good management.
it also depend on the site of the hatchery, equipment, availability of skilled labour etc.
It is pertinent to ascertain the following:-
1. The health and age of the breeders (parent flock)
2. Vaccination status
4. Fumigation programme of the eggs and hatchery equipments.
5. Interval between egg collection and setting Sitting Your Hatchery It is fundamental to locate the hatchery away from existing farms, farm houses and even human settlement. However it should be accessible by good road that eggs collected from breeder farms can easily be transported there. Ensure adequate water and electricity supply to the hatchery. The immediate surrounding of the hatchery should be properly cleaned and kept hygienic at all times. Hatchery wasteshould be properly disposed and incubators thoroughly cleaned and sanitized.
The size of the hatchery building depends on the scale of production, but must meet basic hatchery premises plan.
1) Egg receiving room
2) Disinfection, fumigation and holding room
3) Egg setting room
4) Candling room
5) Hatching room
6) Chick sexing room
7) Chick holding & supply room
Handling of Hatchable Eggs
Hatchable eggs meant for setting in incubators should be handled with utmost care. Fertile eggs should be collected at least three times a day. This is necessary to ensure that they are not soiled and can be cooled faster. Effort should be made to select the eggs by rejecting all those having misshapen size, thin or cracked shells or those that are excessively big.
The eggs weighing between 54 and 64 grams are ideal for hatching. Once they are selected, they should be fumigated with suitable agent such as formaldehyde, dry cleaned or dipped or washed in warm sanitizing agent.
Prior to incubation, eggs can be stored in air conditioned room at a temperature range of between 13-16°C and a relative humidity of 75-80 per cent. To enhance proper hatchability, it is generally recommended that hatchable eggs should not be stored longer than seven days in a controlled room but preferably four days.
