Florida Bullfrog, do your cracker birds have more fire than your "blueface"? I think you said the crackers might be smaller an more athletic but how do they compare temperament wise?
The short answer is that the Crackers are just as gamey as any other gamefowl I've had on the farm. In this context, "gamey" means the mature roosters will fight to the death in a free range setting with their natural spurs. I have no idea whether they'd so fight if they were in a cock-pit 100 years ago wearing steel gaffs or whether they'd run at that point.
By now I've had multiple lines of confirmed gamefowl along with my Crackers and I can offer some better observations as to gaminess across the board as defined by mortal aggression.
All of the gamefowl I've had (with one exception I'll mention shortly) start off submissive as stags, and by stags I mean cockerels just past the chick stag at the point some adult coloration is coming in. They do not fight to the death in a free range setting when they're young. They'll run from the mature brood cock if he bothers them. Even my Aseel did this after getting spanked a bit. As to the brood cock, the mature brood cock generally ignores young cockerels and stags until the point the stags start breeding the hens. Then the brood cock will run off the stags when he sees them trying to breed but it does not result in a death-fight.
The death-fights occur between two mature brood cocks when they're over a year old, closer to 1.5 to 2 years old. At that age, I cannot keep but one free range because they will no doubt about it fight to the point of death or until one has lost both eyes. This is true of my Crackers, my American games, my American game bantams, and my Aseel that I had. I can't mix and match any mature brood cock from any of those lines or else one will get killed.
Indo is the exception. he's always been a crazy suicide charger since he's been about 4 months old. He would run if a mature brood cock scraped him good a couple of times but then he'd immediately charge back in to get more a few minutes later. When he started that I had to pull him off of free range until I rotated out the brood cock. Now I believe he'd stand until dead or severely maimed even though his spurs aren't in yet.
I'd say the "BF" I've had are cooler than my Crackers for the same age, and I have not yet had a "BF" rooster make it to maturity to see how much fire it has. They're not a good comparison because I'm not exactly sure what those birds really are given that one lays blue eggs. Jon Jon was close to that age that the fire should have started coming out at the point the eagle got him. Mongo the Indom, my American that is currently on another farm, wasn't all that fiery until his spurs came in. Now he's fierce.
I've seen enough now that I'm skeptical of when gamefowl guys brag about their chicks killing each other. When that happens I don't think its game drive, its some sort of stress from the conditions the chicks are being brooded in. Although I also acknowledge it can be individual personalty independent of a game drive. I don't think game drive kicks in until sexual maturity. I think one doesn't really know what they have in terms of "fire" in their game cock until he's mature near 2 years old.
I also think maturing in isolation changes the mindset of a rooster. A stag that is never whipped by a brood cock doesn't learn to submit in the same way. I think a stag that is tie corded at a few months old and is never placed with a brood cock is going to charge in full blast if turned on another rooster at 9 months in a way the same stag wouldn't if he's spent those months under the domination of a mature brood cock who teaches him his place in the pecking order.
