This experiment was conducted to compare percent hatch ability, hatching weight and feasability of raising chicks from three grades of eggs (special, A and B) of the New Hampshire breed. This experiment consisted of 12 incubations of 300 eggs each (100 eggs from each grade). Chicks from the last two incubations were raised to 8 weeks of age. Interpretation of results showed: 1 - no difference in percent hatchability between the egg grades studied; 2 - significant relation between weight of egg and weight of egg and weight of chick at hatching; 3 - chicks from larger eggs developed better had higher weight-gain, an lower mortality index.
