A leghorn hen is able to lay more eggs because it is larger than a countryside hen. The ability of a hen to produce eggs annually is more than ten times the weight of the body of the bird. Hence, if a leghorn hen can produce about 265 eggs per year, it weighs at least 2.65 kilograms. The more exotic the breed of poultry, the lower its production of eggs will be. Therefore, there is an inverse relationship between the breed of the bird and its production of eggs.

Countryside and backyard hens are smaller in size that leghorn hens and they are only exception to the hypothetical assumption that the more exotic the breed of poultry, the lower its production of eggs will be. This is because it is fairly common to find hens in the countryside and in the backyards of houses, and they are neither of exotic breeds nor do they have the capacity to produce more eggs than leghorn hens.

Apart from the low weight of the countryside hens, the other factors which affect the production of eggs (which are known as external and internal stimuli) are changes in the hormone levels which affect the condition of the ovaries and the oviducts, the decreasing the length of the day, the process of molting, the health of the flock, the age of the bird, a poor nutritional value and stress.
