Here are the first ones pipping, 4 in total are cracked or have a small hole started.
Chicks have a pipping muscle on the back of their necks. It is this muscle which gives them the strength to force the egg tooth through the inner membrane of the eggshell.
When a chick becomes too large to absorb oxygen through the pores of its eggshell, it uses its egg tooth to peck a hole in the air sac located at the flat end of the egg. This sac provides a few hours worth of air, during which the chick breaks through the eggshell to the outside. The egg tooth falls off several days after hatching. http://en.wikipedia.org/wiki/Pipping_(animal_behavior)
See below, both cracks bottom right. Two different eggs of course. There are 6 eggs left in the ‘bator. The 7th wasn’t formed at all, looked like it was never fertilized. So hoping for 6 chicks out of this batch, and so far 4 have shown signs of life with cracks. So far, the Brinsea is living up to its reviews (and price tag), granted, I still don’t have one living and OUT of the shell 😉
As I’ve been warned, I shouldn’t count my chickens before they hatch!
