Each treatment had 66 eggs with 22 eggs per
replicate. The eggs were fumigated with
formalin on potassium permanganate in the
ratio of 1:2 for 15 minutes and then set into
electric Western incubator with the broad
ends pointing upward. The optimum
incubation temperature was 99.7 °F with
humidity of 83.5% while the hatching
temperature was 98.5 °F with humidity of
85%. Fertility test was conducted on the 18th
day of incubation. Parameters monitored
include incubation weight losses, %
hatchability and % mortality.
