You might do a search on crop surgery - I have seen instructions on here. As far as restraining her, normally covering or wrapping with a towel works best - they are normally pretty docile when their heads are covered. You can normally get antibiotics from the vet or even the feed stores like TSC. I have given antibiotics with an eye dropper, they can also be given in water.
I agree with you that I think the surgery is worth a try if you are up to it.
