Just curious about the saddled air sacs u mentioned, I have done some extensive reading in the last month on the effects of pressure differential in hatching eggs and how it affects hatch rates, I ran acrossed some articles printed by ISA poultry a Hendrix genetic giant from the E.U that flew in 10000 eggs to C.R from France and Spain to establish there highbred laying flock in 2007 and they reported a 60% hatch rate after air transport down from 95% from there hatcheries in the E.U but i guess when u are talking that type of commercial volume a 35% loss is already factored in ,A loss hobbyist like us can't afford to swallow
