^{a, b, c, d} – means marked with different letters differ significantly at P ≤ 0.05; K1 – egg shell conductance constant between EW0 (initial egg weight) and EW1 (egg weight at the start of incubation), K2 - egg shell conductance constant between EW1 and EW2 (egg weight after 14.5 days of incubation), K3 - egg shell conductance constant between EW2 and EW3 (egg weight at the end of incubation)
