Unexpected budgie???????????????????

So one of mine neighbors have a budgie. They found her outside and she doesn't have a band on her ankle. I asked and they said she is aboslutely a female.( I need to really see her) They had her for a couple months, but now they want to either give her to me or set her free. I don't want that to happen to her, but i also want a bird I can interact with. My neighbors have never played with her or taking her out of her cage. No one in there family has tried to tame her. There for I don't know how friendly she is. They apparently grew tired of caring for her. >:( Plus I planned on getting a younger budgie.(They don't know her age because no ankle band) Particularly wanted a male also. For the main reason is I heard females can become eggbound and die. =( I am at cross roads. Save her and give her a better life or go buy a possible young male budgie. PLEASE HELP! =(
