Hi! I recently got a pet bunny (named him Lucah, 3 month old Holland Lop) from a licensed breeder. I’ve only had him for about a week and a half now. A day later after I got him, I was petting his head and I felt some type of scab on the top of his head close to his left ear. I didn’t really think about it much since I didn’t see him itch it constantly and I thought maybe it was a healing bite wound considering he was around other bunnies. A few days later I took a closer look and saw that the scab was slowly disappearing, but that was when the itching started. There seems to be some hair loss, irritation, and dandruff (?) as well. I gave him ivermectin orally yesterday and put miconazole on the area earlier today. Any idea on what it is and advice on what I can do?
This was the day I saw it.

This was taken a few days later.

This was taken an hour ago. I put miconazole on the affected area. I’ve been seeing him itch it more since then.

All replies are appreciated, thank you!
