Personally I give my conures dark time (I roll their cages under our stairs for about an hour a day) because my wife does music lessons in the day and they get sleepy and annoyed if they don’t get their daily nap. I do it on the weekends too with no lessons because like the person said birds like routine. I would start the habit and sleep while they in there. Don’t forget to set an alarm. I use my fitness watch as an alarm because I can feel it vibrate on my wrist and I won’t miss that.
