That's wonderful that you have vets who know about chickens - not terribly common. I agree completely that it's your money, your bird and your life, so cudos on taking her in; I hope she thrives after your love and care. The only thing that I would be cautious about is breeding her..... any bird, no matter how beloved, who is especially needy of human intervention to survive, well, it's not the greatest trait to be passing on to future generations.
Best of luck to your girl!
