Hi, my bunny Septimus has a growing bald patch in the neck area, above his shoulders . It all started about 4 weeks ago when I pulled a small (1.5mm) piece of insect (not a tick) out of his skin. There weren't any head parts, it was more like a piece of shell. The skin was red and inflamed then but the bald patch has grown from about 0.5 cm to 2-3 cm now. He is still lively and eating ok, though might be a bit more tense than usual. No pus or anything so I don't know if it's an infection or what it is. I've tried antibacterial powder but it's not helped and I think it was stinging him a lot. Any advice would be really appreciated, I've had lots of helpful suggestions on here before!
