As far as losing the toe I think she'll adapt as Amiga has said. It's amazing how well they adapt, I haven't ever seen one but have read of ducks and chickens with out 1 leg adapting and saw a video of a chicken that lost her toes to frostbite doing great running around scratching. So that part should be fine,
Like A said the smell isn't good. It may fall off on it's own but what does the rest of the foot look like does it look like the infection is spreading up into the rest of her foot/leg? You might call around and see if you can find a farm vet ask about prices or consultation on the phone. If you live in an agricultural area there are probably those that make house calls. Maybe some bartering? But I really do understand about the expense of getting a vet involved.
Have you been soaking her foot in Epsom salt water also?
