  1. a, b, c, d – means marked with different letters differ significantly at P ≤ 0.05; WL1 – weight loss between EW0 (initial egg weight) and EW1 (egg weight at the start of incubation), WL2 - weight loss between EW0 and EW2 (egg weight after 14.5 days of incubation), WL3 - weight loss between EW0 and EW3 (egg weight at the end of incubation), WL4 - weight loss between EW1 and EW2, WL5 - weight loss between EW2 and EW3
