The video above is really funny. A humorous take on a cockatiel romance. Enjoy!
All these videos show a cockatiel egg hatching.
If you are wondering how long the cockatiel egg hatching process takes, incubation is 18 days from the time the hens sit in earnest, therefore, count a few extra days if sitting is delayed. The actual hatching takes a couple of minutes before the chick pops out of the egg.
