How to breed cockatiels?
Cockatiels are ready to breed when they are between 18 and 24 months of age. They will only mate if they are compatible and you must provide a nestbox for them. If there is plenty of food, they may lay eggs in as little as two weeks, although it is common for them to wait up to two months before lay them. All you can do is provide the best environment for them and the rest is up to them.
