Does your vet have a pain management plan for you? It's going to be a full time job making sure she's eating and pooping normally. You'll need to clean her ear on that side regularly as well.
You may not want to hear it, but there is the very strong possibility that the healing will not go well without surgery. A local shelter will certainly not fault you if you chose to bring her in, and explain that you cannot afford the care she needs. They're likely to get her the medicalattention she requires and find her a nice home once she's healed.
Rabbits are delicate creatureswho's health can go south very quickly after a major injury. Be prepared for high vet bills in the future for the number of check-ups she'lllikely require. Also consider that the next ten years will be spent in the company of a special needs animal, who may reqire help for even simple activities.
Earlier this year, one of my girls broke her leg, also her tibia, and also in two places.It would have needed to be amputated. My vet recommended we put her down. I hope your vet's advice works out for your situation, but do prepare yourself in case you need to take a different road.
Good luck, and please keep us posted.
