Defiantly take her to the vet as soon as you can. There are other factors to this also not just dental.
Also, 6 months seems a little young for a doe to have kits. Having off sprint so young isn’t healthy either.

If it’s somehow related to taking care of rabbit babies, I have no knowledge of that. I’ll only share some information based solely on Meadow herself, rather than considering her as a mother, since I am not experienced with what implications that entails to rabbit health.

Loss of fur and crust development can come from drool, which can be caused by dental issues. Dental issues do range though. Abscesses are a possibility, but there’s also molar spurs (spikes that grow out into the cheeks which typically get ground down by hay, but for some rabbits, human intervention is required to keep them from harming the rabbit), tooth infections (bacteria entering the tooth from a crack that is generally irritating and growing in the tooth), incisor over growth (front teeth are overgrown, causing improper teeth alignment, discomfort, and improper chewing), tooth root overgrowth (tooth root is growing into the jaw), and other potential scenarios. The reason “drool” is a common side effect is because the rabbit is producing saliva in order to lubricate the mouth, trying to make the discomfort more tolerable. The more slippery it is around the teeth, the less spikes may harm them as they chew. A vet, using an otoscope, will be able to peer into the back of the mouth and figure out what may be causing the drool.

An alternative explanation is a skin infection that’s simply showing up around the mouth, rather than being a result from drool. Wick has gone through waves of ringworm, which all begin with fur loss/crust around the mouth, because that’s where he keeps getting exposed to the spores. Ringworm/fungal infections specifically can be confirmed by a vet taking a fur sample near the fur loss, putting a solution on it, and looking at it through a microscope. Cultures can also be done as well. Other rabbit skin-related diseases I can think of around the mouth are rabbit syphilis (which also shows up around the genitals and more so in the lips of the mouth; not just outside).

Keep monitoring and encourage eating, pooping, etc. until you’re able to get to the vet on Friday. Best wishes to you and Meadow!

If it’s dental issues, your other bunnies will be fine. I’m not sure about ringworm and the babies, but if your girl is separate from your other 2 buns, then they should fine as well.

Just to clarify, are the kits getting veggies? Or just your 6 month old?

Sore chin oh no! I’m glad you were provided with an ointment to help her out! Out of curiosity, what’s the ointment and what’s the application schedule (once a day?)?

I’ve never heard of something like this happening, so it’s good to know for future reference. So was she chinning the litter a lot, or getting irritated by it? Any ideas?
