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.
Don't get excited if the dove is not sitting on the egg or is standing over the egg not getting it warm. They will sit on it when they are ready. The incubation will take about 15 days for the eggs to fully hatch. Dove eggs do not have a waterproof membrane like chicken eggs so it is important not to get a dove egg wet.Anything you put on the egg will penetrate the shell and affect the baby inside.ove eggs are larger than those of the average bird. They are a glossy white about 2/3 the size of a golf ball. Sometimes it is difficult to determine which is the small end of the egg and which is the large end. There are usually 2 in each clutch.
