That's good. Noodle my
grinds her beak a lot but it can mean several different things.
If she's puffy and perching it means she's content and happy.
If she's out and pins her eyes and make a loud grinding with an agressive stance she's nervous and it's a warning that if something doesn't move back she's gonna bite.
Sometimes when I rub her neck and snuggle her she makes a loud grinding/clicking and I assume it's because she likes it. She doesn't try and bite me or move away at those times.
The other is she grinds/clicks her beak on things to make a weird grind/click/tapping noise. I don't know why she does that. Sometimes she does that on a mirrow when she see's herself but she's also done it to the lid of my laptop.
