They are on the nest 97% of the time. Especially at night. Mourning Doves sit on their eggs for about 2 weeks, feed the babies in the nest for about 2 weeks and then care for their young for about a month after they've fledged. Both male and female mourning doves share in incubating and feeding their young. I'm sure it will be any day now before you see little peepers.
Female mourning doves feed the young most during the first 15 days after hatching but after that males take over the responsibility for feeding the young. The young continue to stay near the nest and beg for food after they have fledged, but can survive on their own after 21 days old if there is food nearby.ncubation lasts 14 to 15 days. Young mourning doves are fed regurgitated food by both parents. For the first 3 to 4 days after hatching the young are fed only crop milk, an energy rich substance that is produced in the crops of both male and female parents.
