I've mostly seen people say beak grinding is always a good sign that shows that a bird is relaxed and content, or even happy, but I'm wondering if there's any time where this is not the case? Out of curiosity mostly, although I think Sunny has been grinding his beak a little more than usual lately, but I may very well be imagining it at this point lol. He's otherwise mostly fine, though he has been on some medicine after a recent vet visit, but he's now doing much better since he started them.
