Hatching: Cockatiel eggs hatch 18-21 days after nesting begins. A few days before hatching, the air cell (located at the wider side of the egg) will become larger and start to tilt. The baby will then reposition itself and move into the air cell.
Re: male cockatiel age for breeding. I think 10 months is fine for a male....thats when I ussuallu breed mine, by the time they are done raising a clutch and incubating they are a year old.Some people might disagree because they have to be mature but if your paitent enough than you should wait until 12.8 month old Cockatiel= 20 yr old young adult.  http://www.asabirds.org/Cockatiels.htm Cockatiels will mature at about 8 months of age, but it is best to wait until they are at least a year of age to start breeding them. .
