The female will lay 3 to 5 eggs in the nest. They are blue or blue-green. They are 2.8 to 3 cm (1.1 to 1.2 in) long. They are 2.1 cm (0.8 in) wide. Only the female incubates the eggs (incubate means that the adult will sit on the eggs and keep them warm and help the babies inside grow). It takes 12 to 14 days for the eggs to hatch.
