When should you get a breed from Cockatiel birds?
Cockatiels are non-stop breeding birds, but a good breeder always prioritizes the health of their birds.
I would like to share my own breeding method. I only take a breed from my birds once every 4 to 5 months.
When the birds complete one breeding cycle, I separate the female into a flying cage. The benefit of this is that I get 4 to 6 eggs and chicks from the pair in every clutch, and the birds also stay healthy.
The cockatiel is a bird that openly shows its breeding mood, such as the male whistling, and the female bowing her head to touch her crown 👑 with other birds.
