Both male and female crows will build the nest between March and July. The female crow will lay 4-5 eggs with an 18 day incubation period. Young chicks are fledged and ready to leave the nest after 4 weeks.
Young chicks will typically stay with their parents and the rest of the flock even after being fledged and can continue to be fed by adults for another 30 days. Young crows will frequently stay with the flock for the next or even several nesting seasons to help with nestlings.
