The female incubates the eggs, which hatch after 13 to 16 days. The young cannot care for themselves upon hatching. The female broods the chicks for up to seven days after hatching. Fledglings then leave the nest 15 to 20 days after hatching. [11] Juvenile (left) with parent Eastern bluebird at nesting box Eastern bluebird in Quebec, Canada
Both sexes build the nest and rear the young, though only the female broods them. The male feeds the female while she is brooding the eggs. There are usually between 3 and 6 (averaging 4 or 5) eggs laid and incubated over 16–18 days. The young fledge usually between 17 and 21 days after hatching. [32]

The bluebirds are a North American [1] group of medium-sized, mostly insectivorous or omnivorous birds in the order of Passerines in the genus Sialia of the thrush family (Turdidae). Bluebirds are one of the few thrush genera in the Americas. Bluebirds lay an average of 4 to 6 eggs per clutch. They will usually brood two or three times in a year.
Bluebirds have two or three nestings per year so do not give up trying to attract them. Keep monitoring your bluebird nest boxes and make sure that they aren’t occupied by house sparrows.
These eggs are incubated by the female, [14] usually after the second-to-last egg is laid, [54] for 11 to 20 days, [53] although most hatch after 14 to 15 days. About 88% of nests produce at least one nestling, but this can be lowered by poor weather and a younger breeding female. [14] The eggs generally hatch in the order they were laid.
