Hatching Eggs 101 - BackYard Chickens Community
The influence of high altitude on the hatching of chicken eggs.
Because of increased egg shell conductance at high altitude, eggs that were layed at sea level but incubated at 3100m will loose more water than eggs layed & incubated at sea level. Also, eggs laid at 3800m have lower amounts of albumen, less water than eggs at sea level and both egg composition and weights vary as consequence of changes in elevation, eggs produced at sea level are consistently and significantly larger than eggs laid at 3810 m. The mass of the yolk decreases and the albumen increases as sea level compared to 3810. Data suggest increase in mass of eggs at sea level compared to 3810 m is due primarily to water.
