How many days before hatching do you stop turning chicken eggs?

You should stop turning chicken eggs 3-7 days before they are due to hatch. Here's why:

* Positioning: The chicks need to be in the correct position to break out of the shell. Turning them too close to hatching can disrupt this process.

* Pipping: The chicks will start to "pip" (break through the shell) shortly before hatching. Turning them at this stage can injure them.

* Natural Instincts: In nature, the mother hen will naturally stop turning the eggs as hatching approaches. This allows the chicks to settle into the best hatching position.

Here's a general timeline:

* Days 1-18: Turn the eggs 3-4 times a day.

* Days 19-20: Reduce turning to once or twice a day.

* Days 21-21 (Hatching): Stop turning completely.

Important Note: These are general guidelines. The exact timing will vary depending on the breed of chicken, the incubation temperature, and other factors. Be sure to consult your incubator's instructions for specific recommendations.
