Nestle the dove eggs in the incubator. Turn the eggs every four hours to promote proper development of the baby doves. If you don't turn, the doves could fuse limbs together or develop other health problems. If you are using an incubator that automatically turns the eggs for you, you can skip this step.t this time, place the eggs in a hatching basket or lay them on a cloth. Allow the baby doves to hatch unassisted. Once started, the hatching process generally takes 24 hours. If you try to help, you risk harming the dove. Remove the hatched doves from the incubator. Give them water and dove food.
Fledglings: From the time they hatch, doves leave the nest at about 11 or 12 days old. When they begin to self-regulate their body temperature, the parents no longer brood them at night. If a baby is reluctant to leave the nest after 12 days, the parents will often keep watch nearby but refuse to feed it.
