What changes the large parrot questions answer
Plan daily out time before adopting a cockatoo, and make that time active, supervised, and predictable.
Use stations and jobs
A play stand, training perch, foraging work, and chew items help the bird succeed outside the cage.
Do not over-cuddle
Cockatoos need connection, but constant body contact can feed dependence, frustration, and screaming.
Make the room safe
Doors, windows, fans, cords, kitchens, furniture, other pets, and chew hazards must be controlled every time.
Best routine
Shorter structured sessions every day beat chaotic freedom followed by long cage boredom.
