When Do Cockatiel Eggs Normally Hatch?

I know that fertile cockatiel eggs hatch eighteen - twenty one days of incubation, but I was wondering what is the most regular day they hatch? Do they normally hatch on the eighteenth daytime, nineteenth day, twentieth day, or twenty first day?
all right chicks usauly hatch after 19 -20 days in my experience.say hi to diablo and grey grey from me!
Mine first egg generally hatched around day 20 but it can thieve longer than 21 days so don't take them out if they don't hatch by then, bestow them in up til a week after.

You must be really excited..
Answers:    omg you wont believe this but my cockatiels are sitting 4 eggs too
Anyways they hatch on the 19-21 light of day.
It depends on when the mother bird started incubating.
Honestly, it does vary from 18-21 days from the day they start sitting on the eggs. It is exciting to look forward to though. :)
Where to buy a galah?   Does heat (when incubating) determine the sex of a kid budgerigar?   My canary have trouble settling surrounded by for the dark.?   My birds never cooperate beside me?
