You can use manukka honey on wounds on rabbits, but I would NOT use it on her without asking your vet if it’s ok to try. The “problem” with manukka honey is that its very very tasty, so the risk is she’ll want to clean her face with her paws to get to the honey. This could make matters worse, obviously. You would probably need to put a cone on her to prevent her from tampering with the wound.

It does look weird.

I come to think of rabbit syphilis, treponematosis, but the placement of the wound is not typical. For rabbit syphilis , a week of normal rabbit abx would make no difference.

Have you tried a different vet? One rabbit savvy? You did not mention what sort of testing may have been done. Throwing antibiotics at a wound without knowing the cause seems pretty low commitment so I’d encourage widening the search for a vet with good rabbit experience and expertise.

At this point, I’d think there is concern for both the initial cause of this, in addition to what may be some consequences of it continuing for so long. Blood work, head x-ray, sampling, for example, would all be informative diagnostic assessments.

Did the vet confirm that this isn’t an abscess? Is the wound just on the surface or does it go deeper?

I too was think perhaps there’s an abscess underneath. In that case, if a course of antibiotics doesnt help (although one week is often to short a time), the abscess probably need to be opened and cleaned out, then be kept open so it heals from the inside and out.
