Production Parameters. At the end of incubation,
the number of hatched chicks was
recorded. Every chick was weighed and examined
macroscopically to score them for classification
into high-score or low-score chicks for
quality measurement. A chick of good quality
(saleable) was defined as being clean, dry, and
free from deformities (no skin lesions, wellformed
beak, normal conformation of legs),
completely sealed navel, and no yolk sac or
residual membrane protruding from the navel
area [9, 22]
