During incubation, it is recommended to turn the eggs at least three times per day, but no more than every hour. This helps to prevent the embryo from sticking to the inner membrane of the egg and ensures that the developing chick receives adequate oxygen and nutrients.
It is important to turn the eggs evenly and gently to prevent damaging the embryo or disturbing the developing chick. You can mark one side of the egg with an “X” and the other side with an “O” to help keep track of which side has been turned.
However, on day 18 of incubation, the eggs should be stopped from turning and allowed to remain in the same position until hatching. This is because the chick will be positioning itself for hatching during this time and needs to be able to settle into the correct position for a successful hatch.
