so sorry for what you and prettie are going through. I would think twice about giving her to a new home. she knows you love her and she loves you. cockatiels hate change, and she is already stressed because of her wing problems. and, it sounds like you are doing as much as possible to help her, what more can another person do? I don't know how shelters for birds are by you, but the one closest to me (I'm in Wisconsin) is not very good. shelters often are overwhelmed by amount of birds they have to care for, she will probably get less attention there. I think you are a wonderful and caring person. just keep following vet instructions, it may take a while for her to eat healthy, but if offered daily, she will most likely start to like some of it. you may want to eat peas or corn by her, offer her a taste. my birds like to eat off my plate. and, I may sound nuts but this worked for me - my cockatiel, 6 mos old at the time, caught one foot in something and lost the whole nail, it bled a lot. I put her in cage, she did pick on it at first. I told her don't pick on it, it will bleed more and hurt. she did not pick on it again. it healed well.
