ANATOMY

Detailed explanation-1: -Eggs must be turned at least five times every 24 hours. Turning more frequently is better and once per hour is best. Keep accurate records to ensure the eggs are turned three to five times each 24-hour period.

Detailed explanation-2: -By turning the eggs, the yolk turns within the albumin, once again moving the yolk away from the shell and making it safe for the embryo on top until it is time to turn again. Eggs will need to be turned a minimum of 3 times per day, and 5 times is even better.

Detailed explanation-3: -Eggs must be turned at least 4-6 times daily during the incubation period. Do not turn eggs during the last three days before hatching. The embryos are moving into hatching position and need no turning.

Detailed explanation-4: -Research has showed that egg turning is critical in the first week of incubation, especially first 3 days. It has also shown that after 15 days turning it is not necessary and stopping will not affect hatchability.

Detailed explanation-5: -Early observations of feral chickens suggested that a brooding hen turned her eggs as often as 4 times per hour (96 times daily) during early incubation but modern incubation technology has settled on the more convenient once per hour (24 times daily).
