When domesticated, these birds make for low-maintenance and lively pets. In captivity, they love human interaction and companionship with other birds.
Stresses for birds can arise from any number of factors. Changes in owners, environments, food, and even feeding times can cause undue stress for your bird.
You should look out for specific cockatiel behavior and body language during specific periods.
If you see your bird getting ready to lay eggs, make sure you provide them with a vitamin and mineral-rich diet.
