How does the 5-pound Leghorn laying 300 eggs compare in efficiency calculation to a 7-pound Orpington laying 200 eggs?
The Leghorn wins when measured by egg mass output versus total annual feed intake.
Efficiency in poultry keeping, particularly when focusing on eggs, is calculated by balancing output against input. Although both birds may have similar feed consumption rates relative to their individual body weight, the Leghorn's superior production volume changes the overall equation. By laying 300 eggs compared to the Orpington's 200, the Leghorn yields a greater total mass of eggs relative to the total annual feed consumed across the year, making it the winner specifically when efficiency is measured by egg mass output versus total feed intake.
