The gestation period, or incubation period, for pigeon eggs is approximately 17 to 19 days. The exact gestation period will depend on the species of pigeon.
The Rock Pigeon, also known as the common pigeon, tends to have approximately one to three eggs in each clutch and has one to six broods. It also has a nesting period of approximately 25 to 32 days that follows the gestation period. The pigeon eggs will be laid in a nest that is usually made out of materials such as straw, stems and other thin lightweight items. The reason that the nests become strong is that the pigeon will use the same nest repeatedly and will defecate in the nest allowing build-up of materials to make the nest strong.
