How long can pigeon eggs live without its mother?

Pigeon eggs cannot survive without their mother or an incubator. Pigeons are altricial species, meaning the chicks hatch helpless and rely on their parents for food and care. Pigeon eggs typically hatch after 18 days of incubation, and the chicks remain in the nest for another 4-5 weeks before they are ready to fledge. During this time, the mother pigeon provides the chicks with warmth, food, and protection from predators. Without the mother, the chicks would not be able to survive.
