Parakeets can breed year round if conditions are right in their environment. Normal breeding season begins early in the year and continues until fall. It is very rare to see parakeets mating, but a male and a female must mate to keep the eggs fertile.
BREEDING HABITAT: Separate flocks of gobblers and of hens break up in late winter as breeding activity begins. Mating occurs in late winter and early spring (March and April) and egg laying begins. The hen lays about 1 egg per day until the full clutch of about 10 or 11 eggs is complete.
