First time hatching question

[greenchickenman]

I heard of couple of my chicks making some pecking noise inside their eggs yesterday. Now today I hear nothing. I'm not sure exactly what day it is in the 21 day process. I just know they should have hatched by Saturday. Next time I will do better about writing the date on them. My question is when you hear them for the first time how long usually is it when they hatch? I have the humidity at 70 percent and quit rotating them. I want to help them out of the egg but I'm sure that's not a good idea. I just don't want them to die on the last couple days

Hello!! do you have an update!!!

PLEASE READ the above ARTICLE IN ITS ENTIRETY BEFORE YOU begin an assist​

below is a paste from the article....​

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!​

Let them go another day or two, then look at the "Assisted Hatch" link in the last post. They should be fine if you are very careful.

Thanks sally and lover 11. I still don't hear anything. Something happened to incubator and temperature rose last night to 104 degrees! It was that way all night until I looked at it in morning. Now I'm more stressed that I cooked my remaining chicks. Thanks for the link and advice, I will leave them alone. I will update with anymore changes. Keep your fingers crossed.
