4th Annual BYC NYD Hatch-a-long

Understanding The Hatching Process

Between the 15th and 16th days, the chick orients itself so that its head is near the air cell at the large end of the egg. Not long before the chick is ready to attempt to make its way out of the shell its neck acquires a double bend so that its beak is under its right wing and pointed toward the air cell.


21 DAYS is just a baseline for hatching eggs.
Many chicks can take 23 - 25 days!
Some pip internally and fully hatch in hours while others will be 24 hours or more.


Egg movement! Eggs can “Rock n Roll” days before they are due to hatch!

The initiation of hatch occurs partially from the increased carbon dioxide level in the egg. This process causes the embryo to begin twitching it's muscles allowing the inner shell membrane to be punctured by the egg tooth. The chick then begins breathing the air in the air cell. Using its egg tooth, it pecks at the shell thousands of times and after a few hours the chick pips a small hole through the shell and begins to breathe air directly from the outside. After the chick has made a hole in the shell, it stops pipping for 8+ hours sometimes up to 24 hours and rests.
During this time, it is acclimating its lungs.


After the resting stage is completed the second stage of pipping begins. The chick begins to turn slowly inside the egg. As the chick turns counter-clockwise it uses the cutting edge of the chick tooth to chip away. As the chick progresses in its movement around the shell, it begins pushing on the large air cell end of the egg. Squirming and struggling! YES STRUGGLING! The chick works feverishly pushing at the cap. Finally with a shove the chick breaks free from the shell wet and exhausted. When the chick is freed completely from the shell it lies still. Its energy has been virtually exhausted, and it is extremely tired. After resting the chick begins to gain more and more energy and coordination of its muscles.

In regards to opening and closing the bator to remove already hatch chicks; It is important to remember that chicks can go 3 days without food/water. It is better to wait for the remaining chicks to hatch to insure reducing the impact to unhatched pipping eggs.

But my new chick is running around in the bator knocking eggs around!
LET THEM GO! DO NOT OPEN THE INCUBATOR! They are fine!
oops.. i just opened the bator twice to get new chicks out, will they shrinkwrap? it was only for a second
 
Quote: I thought is was odd too when we first started. Sebbies hatched from ALL white stock with no color in the genetics can "normally" be gender ID'd at hatch by color. Always best to confirm with vent sexing as sometimes oddities will pop up.
Quote: yep............but also know goose eggs dont ship extremely well (worse than chickens) and it takes 6+ eggs shipping to get 2-3 to grow and thats considered good
 

















These are the babies from yesterday 8/9 buttons hatched yesterday ( the last one hatched befor I got up this morning) and 1/2 cortunix eggs ( the second hasnt done anything yet) 1 pip in a pretty percarious spot in the serama eggs as of this morning.
