What’s going on here??

My blood parrot has started doing this in the last few days. They are very young (body about the size of a ping pong ball) so I don’t think it’s mating behavior... but what do you think? Any opinions? Does this mean they’re happy?

It is either digging a pit to put babies in or excavating a cave to hide in.
