Re: Bed time
What do you mean by "sleep pen"? I'm assuming it's just a regular cage, only smaller than his main-cage, but I wasn't sure...The other question is where is his sleep-cage located in your house? Is it in the same room that the people of the house are in, or is it in a dark, quiet room? Do you cover his sleep-cage with a dark-colored sheet/blanket or a bird-cage cover?
If you have his sleep cage located in the same room as you and others are in and awake in, then you might try moving his sleep-cage to a room that no one will be in the rest of the night, with the lights off and the door shut...And if you already have his sleep-cage located in a different room with the lights off and the door shut but you don't cover the cage with anything, you might try that, covering it with a dark-colored sheet, blanket, or an actual bird-cage cover that you can buy at any Petco/PetSmart...
As far as what is in his sleep cage, it should be sparse. No food at all, no toys, nothing that they can play with, chew on, etc. And it should be much smaller than his main-cage, in fact it only needs to be large enough so that he can open up both his wings fully and not touch the bars with them or his tail. That's it...I have my 4 larger bird's sleep-cages in my master bedroom, and they all go to bed between 8-9 usually. I say "It's bedtime! Night-Night Sleep-Sleep!", my Quaker Parrot will start yelling "Sleep Sleep Sleep?", I say "Yep, Sleep Sleep Sleep!", and then all 4 of them head upstairs to my bedroom and go right into their sleep cages (except for Duff, my Cockatiel, who has to hitch a ride on me because she can't fly well-enough due to a wing-injury)...Their sleep cages are small, and they each have 1 perch, a swing, and a water bowl with fresh water in them. That's it. And I cover each of them with a sheet and shut the bedroom door...I usually come back up to bed a few hours later, and they usually don't even make a peep when I come in and go to bed...They do however wake me up as soon as the sun starts coming up, but you'll have this, lol...
The other thing to try is what Itzjbean recommended, maybe keeping him up for an extra hour than you usually do, it might be that he's just not ready to go to sleep...Most parrots actually put themselves to "bed", meaning that even if they are out with their people/person, they will end-up going to sleep on their stands, perches, cage-tops, on their person's shoulders, or if they sleep in their main-cages they often just put themselves to bed when they are tired. My mom's African Gray has always put himself to bed...it's hilarious, we'll be in the living room watching TV or playing a game, talking, whatever, and he'll be there talking-up a storm or cuddling with us, and then suddenly we look around and he's gone..He just suddenly says "okay, I'm tired...Night!" and sneaks-off to his cage and puts himself to bed...
So it may just be that your guy isn't tired enough at that time of night. If you already have his sleep-cage located in a dark, quiet room where he can't hear that you're still up and around (that's a big deal, if he can hear that you are still awake then that might be keeping him going), and if you are already covering his cage, and neither of those things are helping, then I'd try keeping him up for an extra hour and see if that makes a difference...Or not put him to bed until you see him falling asleep or at least "fluffing" himself up, yawning, etc. Then put him to bed...My Green Cheek will be playing at night on the play-gym and then suddenly he'll fly right over to me while I'm usually on the couch reading or watching TV, and he'll plant himself on my shoulder, fluff himself up, yawn, put one leg up, and he's out...
