D Correct answer
Explanation

In the poultry industry, production of hatching egg is more expensive because it requires optimum temperature fo incubation. But the major factor is the weight of the hatching egg and chick weight. Under optimal egg storage and incubation conditions, chick weight is 67-69 per cent of egg weight at setting. Therefore, the more uniform the egg weight, the more uniform the chick weight. Breeder uniformity determines uniformity in the hatching eggs produced; the more uniform the breeder flock, the more uniform the egg weights. Hence, some of the eggs produced by hatchery flocks are not acceptable for incubation and is rejected. So, the production of hatching eggs is more expensive than the production of market eggs.
