Abstract
FRAPS (1955) indicated that the chicken had a greater interval between the last two ovipositions in all sequences of three or more eggs than between any other two eggs. He also demonstrated, based on the data of Heywang (1938), that the lag time of the terminal oviposition decreased as the sequence length increased from 2 to 7 or 8 eggs. Lag times between the initial and terminal oviposition continues to decrease, approach zero or even fall slightly below zero as the sequence length increases. The data of Heywang (1938) as analyzed by Fraps (1955) indicate that the total lag increases from approximately 4.2 hours in the 2-egg sequence to approximately 6.7 hours in the 6-egg sequence; thereafter, it remains fairly constant.That turkey hens lay more of their eggs in the afternoon than in the forenoon has been shown by Stockton and Asmundson (1950, natural light program), Kosin and Abplanalp…
