Effect of Clutch Size on Efficiency of Heat Transfer to Cold Eggs in Incubating Bantam Hens

  • Øivind Tøien
Part of the NATO ASI Series book series (ASIAS, volume 173)


The brood patch works as an important organ of heat transfer between the incubating bird and the eggs by increasing circulation when exposed to cold. (Midtgård et al., 1985). The heat loss of the bird to the eggs has to be compensated by increased heat production.
