How many clutches do need for cockatiel before they lay egg?

Cockatiels typically require one clutch, or a set of eggs, to start laying. However, the number of eggs in a clutch can vary, usually ranging from 2 to 7 eggs. Factors such as age, health, and environment can also influence their breeding behavior. Once a female cockatiel is ready, she will lay eggs regardless of whether a male is present.
