Hi,
I find most of my fuzzballs get cranky if not allowed to sleep at least 10-12 hours a night.
I try to put my grey and ringneck to bed around 8 pm....my little ringneck likes to play hide-and-seek when its to time to go to bed...so sometimes, 8:30.
Conversely, my conures are crazy. All they want to do is play. play play play. If i cover them, they play. If i shut the lights out they whisper to each other...they are just a colorful bundle of nuts and crackers. They usually burn out by 11pm...but they wake up later as a result.
I have budgies as well. Lots of them. If they stay up more than 12 hours a day, they start breeding so I try to put them to bed an hour before sundown.
I hope this helps!
