I am new to raising Gamefowl, having only raised a variety of egg laying breeds and Cochins. Gamefowl are definitely more engaged. Mine are only four weeks old, and they make eye contact, move much more like a flock, and have developed much for quickly. Mine can easily fly up 4 or 5 feet, and they are very fast (hard to catch).
On the other hand, mine at three weeks attacked one of their own and nearly killed her. I don't know what set them off, but keep in mind that although chicks of all breeds fight, the differences that these can do damage.
I myself have a lot to learn, but I encourage you to ask very specific questions. People here are always willing to help. The one thing I would add is to plan in advance how many roosters you are going to keep and how you want to house them. I am only going to keep two, because I am new to this and want to keep my learning curve as smooth as possible. Also, I don't think my neighbors would appreciate it if I had 10 roosters crowing all the time.
