Owls usually lay between 2 and 5 eggs, depending on the species and food availability. Some small owls may lay only 2–3 eggs, while larger species can lay up to 6 or more in good conditions. Unlike many birds, owls lay their eggs one at a time over several days, not all at once. The female begins incubating immediately, which means the chicks hatch at different times. As a result, older chicks are often bigger and stronger than their younger siblings. This unusual timing helps ensure that at least some chicks survive when food is scarce. Overall, owl clutch size and timing are perfectly adapted to their environment.
