It’s been a while since I’ve posted here, I had a few concerns. Fluffy has some dry, white little crusty spots on her ears, I’ve attached pictures below. She has one on the other ear as well. It looks like dry skin to me but I’m not familiar with ear mites, does this look concerning?

I also noticed two tiny black flying bugs crawling in her head/nose area the other day. I removed them and inspected her and didn’t see any more. I’m not familiar with fleas or what they look like so if anyone has any insight on this that would help!
Third, I’m curious if anyone has noticed their bunnies slow down with age… but also seem more depressed? Fluffy is 7 now and she doesn’t do much. She wasn’t always the most playful bunny but there are times now when she just sits and faces the wall looking depressed. It’s sad to see
She’s also had a lot of health problems over the years and suffers from urine incontinence so it might be pain-related as well. Just wondering if anyone has noticed depression in their elder buns?
