Development of a Chicken Inside the Egg

May 30th 2007 11:13
Chicken egg incubation can successfully occur artificially. Nearly all chicken eggs will hatch after 21 days of good conditions - 99.5 F (37.5C) and around 55% relative humidity.

The pictures below show what happens inside the egg and gives an amazing insight into the development of a chicken embryo over its 21 day incubation period. You can see more pictures of the process here.

they are not killed, eggshell can be removed by vinegar without damaging the chick
