Since, insertion of the year 1986, the Company of Karamsar has pioneered in the art of Manufacturing Poultry Appliances in India.
1. Hatchability is more than mere fertility. It is a combination of two factors, fertility and viability, the strength of spark of life. The first essential to maximum hatchability is the quality of egg itself. Egg quality is first determined in the flock by:-
(a) those inherited characteristics which affect hatchability
(b) nutrition and
(c) the quality of flock management and the health of the flock.?
2. Initial egg quality, however essential though, is beyond our scope as manufacturers of incubators. It is equally important as to what happens to the egg between the time it is laid and the time it is placed in the incubator. If initial qualities of fertility and viability are to be preserved, then proper cooling, good sanitation, cleanliness, careful handling and storage (small end down) at correct temperature and humidity, under proper conditions, and for not over a safe length of time, are the various factors which have to be observed and followed.
1. Proper embryonic development and metabolism require the correct balance of oxygen supply, carbon dioxide removal, heat and moisture. All sides of the eggs must be exposed to uniform conditions. The essentials for good incubation, therefore, include correct levels of temperature, humidity, supply and air circulation, periodic turning and careful sanitation and fumigation.
2. Even though approximately half of all oxygen consumption, carbon dioxide elimination, animal heat production etc. occurs during the hatching period alone, the success of the hatch is not determined in the hatcher. Unless conditions of incubation have been right throughout the development of the embryo in the incubator, no hatcher can produce miracles and salvage the hatch.
3. Of all the factors of incubation, temperature is the most dramatic in terms of its affect and is the most important single factor. Improper temperature can retard or accelerate the hatch and thereby greatly affect its quality as well as percentage. Hatch in time is very important. Too much of an extreme in temperature, either above or below normal, can kill the entire hatch.
4. Humidity plays a vital role in the percentage of hatch and even more so in the quality of hatch. The combination of too high a humidity in both setter and hatcher can result in drowning the chicks in the shell. Too low humidity in incubator will result in 'dry sticks' Too high a humidity in hatcher during the first twenty-four to thirty-six hours can result in rough and unhealed navels, although this condition is more frequently due to excessive incubator temperature. Too low a humidity in the hatcher can result in chicks which pip but fail to get out of the shell.
5. Proper circulation of air is the key to control temperature and humidity. It is essential that the three factors of temperature, humidity and air circulation be properly co-related for supply of oxygen and the removal of carbon dioxide.
6. An egg which is both fertile and high in viability will hatch even in the face of astonishing abuse. An egg which although fertile, is low in viability, will hatch only if all the conditions are favorable. The greatest source for success or failure in incubation are the eggs which are marginal in viability. Such eggs will hatch if everything along the line is 100%.
7. It is not easy to remember as to what was done to the incubtion three weeks before. Careful record is therefore, essential to obtain maximum results. The method by which eggs were handled, conditions of temperature, humidity and ventilator settings used throughout the incubation period, should be recorded. Then you are in a position to analyze your results in an attempt to determine what might have been the cause of any deficiency in your hatch. To improve your hatchability, carry out a careful post mortem of the eggs which fail to hatch. Such post morterns require time, but they will pay handsome dividends. Through an analysis of your records and of all the factors of the incubation, you will be able to correct your procedures so as to prevent recurrences of any condition which caused trouble.

Careful Culling and flock Selection for high hatchaability.
Raise males together. Use 4 to 7 males per 100 females with light breed chickens,
5 to 8 males per 100 females with heavy breeds. 8 to 13 males per 100 females for turkeys.
Do not use old males, unless proved valuable breeders.
Use properly balanced feed of high quality. Provide adequate waterers of good design well distributed, so that, all birds can have easy access to fresh water.
Provide adequate floor space per bird in housing.
Use early hatched cockerettes timed for best maturity.
Dub males to prevent this problem, and also improve fertility.
Carry out approved disease control practice.
Gather eggs often, cool properly and quickly.
Proper conditions for egg holding be observed.
Gather eggs often. Coo! properly and quickly. Refer instructions for egg holding.
Check accuracy of thermometers, Operate incubator at proper temperature.
Refer instructions regarding fumigation of eggs in the incubator.
Do not set eggs from birds with frozen combs or from diseased birds, particularly those infected with pullorum or other salmocilla diseases.
Feed properly balanced ration of high quality.
Careful culling and flock selection for high hatchability, improve breeding for high hatchability.
