  1. EL egg length, EW egg width, WE weight of egg, IP incubation period from eggs laying to time when the neonates begin to slit the shell, HD hatching duration
  2. *n.d. represents no data, this egg did not hatch (probably infertile egg)
  3. **Mean and S.E. from only 5 individuals, except the first three columns
