my dangerous fighter rooster 😡😡😡

The rooster you are looking at is my home breed. I bought it for 20 dollars, and today its value is 500 dollars. This is not an ordinary rooster; it is a fighter rooster. I entered it into 7 fights, and it won them. It even killed two other roosters. It is very aggressive. Now I have put it into breeding because I want to get chicks from it. I hope its offspring will also fight well.What do you think — should I sell it for 500 dollars, get chicks from it first, or keep it with me as well?
