| Abstract;The amount of calcium, magnesium and phosphorus in the shell portion (shell with shell membrane) of eggs of guineafowl and chicken at various times during the stay in the uterus was measured by an atomic absorption spectrometry or colorimetric method. All of the minerals were found to increase during the stay in the uterus, but the aspect of the increase differs between the minerals: parabolic in calcium, linear in magnesium, and quadratic in phosphorus, and also differs between the guineafowl and the chicken.
