Kai has a tad bit of trouble when going to bed. We put her to bed around 9-ish and we cover her cage with a white bed sheet. We are on a bedtime scheduled so its lights out at that time and my bedroom door is closed. But when she is being covered she starts squawking bloody hell and continues that for around 15 mins. Excuse my language. But this is not every night. Sometimes she does good and is put to bed with no fuss and sometimes the total opposite. Is there any way I could stop this?
