This is correct but don't explain it. I think that frango refers to the type of meat (here from a chicken). Like you have carne bovina (beef) e carne suína (pork).

I believe that "Frango" is the meat while "Galinha" is the living bird.

Here you find more information on it: http://www.duolingo.com/comment/69586

It's actually the same. Frango for an alive chicken and frango for a fried chicken.

Galinha in portuguese and "gallina" in spanish is the word for an adult female chicken that can also be eated an you ca say: "a menina come galinha"

nope there the same thing its just that other might say something different
