Breeding season lasts from April to July for the American Robin, and its eggs hatch in about fourteen days. European Robins begin their mating season in March, and their eggs hatch in roughly the same time frame.
The American Robin will see their eggs hatch in about fourteen days, after a mating season that lasts from April until July. The European Robin, a cousin of the American Robin though not as large or brightly colored, has roughly the same incubation period. Their breeding season begins in March.
Until they hatch? Well, that really depends. The duck sits on her eggs for 28-30 days until they hatch. The father duck is not around. When they hatch, she will lead them to a nearby body of water. Muscovy eggs take 35 days to hatch.
