How long does it take a blue bird egg to hatch?

Answer 1

The total in hours would be 423, 25,920 minutes, or a total of 155,520 seconds.

Answer 2

12 - 14 days
Both male and female bluebirds take turns incubating their eggs for about (13 to 15 days) or two weeks.

Young bluebirds grow fast, but they usually cannot fly on their own until about 20 days. (It is safest not to open the nest box after their twelfth day to prevent premature fledging and subsequent exposure or predation.)

If the clutch does not hatch at all after 3 weeks remove nest and eggs to re stimulate hatching.

Try not to disturb an incubating female during the first 3-4 days, she will desert if feeling threatened.

Answer 3

If you found it out of a nest probably never. I hope you are keeping it warm.

Answer 4

A while.
