Why sleep matters so much
Sleep-deprived birds are often grumpy, nippy and more prone to feather plucking and hormonal problems. In the wild they get long, dark, quiet nights, and pet birds do best with the same — roughly 10–12 hours, on a consistent schedule.
Setting up good sleep
Keep the sleeping area dark and quiet, away from TVs, screens and busy household traffic. A cage cover or a separate quiet sleep cage helps. Try to keep bedtime and wake time consistent, since erratic light schedules can trigger hormonal behaviour.
