Frango vs Galinha

This is a very curious thing, indeed. I actually had to do some research before posting a reply :)
 
First let's agree that we are talking about chickens and roosters.
 
Frango (masculine) and franga (feminine) are young birds usually between 3 and 7 months old. Usually the males are used in cooking because the females are used to lay eggs and are only used in cooking after they reach an older age.
 
When the frango and franga are 7 months old, they are called galo and galinha. Cooking sites say that their meat is tastier than that of the younger ones.
 
Now here's where it is tricky: When we cook the bird rotisserie style, we call it frango or galeto. To be quite frank, I don't think that it means that we are eating the young ones. I think that what we have here is a different naming pattern. Maybe professional chefs know what they are buying and prefer to cook certain dishes with frangos and others with galos. For most of us, I believe we name it accordingly to the way we cook it:

• rotisserie chicken = galeto assado
• baked in the oven = galinha assada or frango assado
• cooked in a pan on the stove top = galinha

 
I'd love to hear more about this!
 

 Where is Nando Brazuca when you need him?  

 In the Churrascaria, we call the regular chicken over 7 months, frango or to be more correct here in america we should say franga because they would be the female of the species. But the Cornish Hen we call it Galeto which I'm not sure if it is proper to call it that being a 'hen' but that's our terminology.

Thanks for the post !
I call it just like Luciana explained... galeto assado for rotisserie style chicken / frango ou galinha assada if it is baked in the oven, and galinha when fried or cooked in a pan on the stove top.
when it is cooked on the stove top...my favorite is when is cooked with sauce. Then you eat with farofa, feijao verde (green beens boiled first, then fried with diced green pepers, onions, and tomatoes) . To make it perfect...pure de batatas. yummy!
