Holistic Rabbit Ear Mite Treatment

This is our first go with rabbits and one of the does we got came pregnant, surprise!..While the rabbit colony is being built, we set her up in her own hutch and she had her kits on New Years day. A few days ago I noticed her left ear had brown, waxy, flaky residue and after researching, it is definitely ear mites. I’m only interested in holistic and natural treatments as these are our meat rabbits. I’m following the protocol I found on https://riseandshinerabbitry.com/2012/10/30/ear-mites-causes-and-remedys/
and using the olive oil concoction. I mixed 1/2oz olive oil with 1ml vitamin E(it calls for 400 IU but all we have is a bottle of it and I don’t know how much 400 IU is..) and a few drops of tea tree oil in a dropper bottle. I’ll be applying the treatment on day one by placing 2-3 drops in both ears and gently massaging the base of the ears. You may also use a cotton ball to coat the inside of the ear. On days 2, 4, 6, 8, and 10 repeat same treatment as day one. Treat again on days 14, 21 and 28. With this treatment, your mite infestation should be gone. Ear mite eggs live for 28 days so by following this treatment plan you will break the life cycle of the mites. Remember you only need a few drops, do not overdo it.

HOWEVER, you’re supposed to remove the rabbit from its habitat, clean & sanitize it and house them in a separate place for at least 3 weeks while treating to ensure their original housing is free of mites and that they don’t reinfect their housing while shaking their head. We will not be doing that as she has 9 of her kits that depend on her. Instead I’ll be applying the oil concoction every other day to the mama and her babies(as preventative) until we have the colony ready for them and they are free of ear mites. I’ll also be adding a few tablespoons of apple cider vinegar in their water to act as a repellent and general tonic. Not sure if it’ll work, but this is the best we can think of to do in this situation.
If anyone has a similar experience or any other holistic treatments, please share🙏

Off the top of my head, it seems like you're doing all the right stuff. I'll mull it over, and see if there's anything in the far reaches of my brain, that we've also done. Just for the record, do take care with the tea tree. Garlic (minced and gently warmer, then cooled & strained) frankincense, and even just plain olive oil are all very effective. I can't recall whether rabbits are one of the critters for which tea tree is toxic, but it is, for dogs & cats. For that reason, I do garlic &/or frankincense, so it can be used for all my critters, and works on a wider variety of things, like mites, ear infections, flushing out foreign matter, etc. Anyway, I'll dig a bit, through both my brain and the parts of the web hidden behind pay-walls (that I have access to), and see if I can come up with anything else.

In the meantime, would it be possible to temporarily move mama & kits to a box, to allow a strong solution spray of apple cider vinegar to soak in, to their current living quarters, then air out?
