That’s actually a very normal time for buns to be active. Many BBers here often talk about their buns waking them up with cage rattles or even jumping up on their faces! My Bumpy used to rattle to come out, but now that he’s a bit older, he’s adjusted to our schedule and doesn’t ask to come out anymore. He just waits, cuz he knows I’ll be opening the door up as soon as I’m good and ready.
The blanket may help you extend his “nighttime” and allow you a bit more sleep, it may take a bit of time for him to adjust though. Do you call out to him when he’s doing this? He’s still so very young, and he might be also starting puberty so may be slightly more assertive!
Bumpy is just over a year old now, he’s never really listened to me when I’ve told him “no” or “stop” before, BUT! yesterday he was doing something I didn’t want him to be doing, and all I had to do was say his name in a stern voice, like I was warning him, he immediately stopped what he was doing and ran over to me. I was shocked!
I guess the best thing I can tell you is that in time he’ll adjust to you, and as he gets older he should calm down. If you are planning on neutering him (if not already done) that may help some of his frustration with the violent cage biting that you are seeing.
