Thanks for the reply. So I guess the reason why you can't let a gamefowl "work it out" with a farm fowl is because the risk of a broken necks/back.
Only if you don't want to lose a farm fowl, I have never seen any farm fowl (Even large breeds like the Rhode Island Red) that were accurate/strong enough to do any real damage unless they were at it for a long time. But American Game, Shamo, and various other Oriental game have and can break backs, necks, and cause enough head trauma to kill a bird with one blow. Not common, but it happens. As read about in a earlier post on this thread, gamefowl (regardless of AG or Oriental) can sometimes even break their own legs with the amount of force they use.
But in a hypothetical sense, there wouldn't have been much reason to let a game work it with a farm fowl. Most farm fowl can't handle a gamecock too long before running, the ones that have are usually half game to begin with instead of pure heritage breeds. But even then, they are no where near as good as even some of the worst true games because of their lines carrying a breed that was never bred for it.. Which would make all tests useless; if a cock does lose to a heritage breed then you know he was horrible except in some cases.
Case in point: A long time ago, back when we had a lot of birds, we had a lot of cocks on tie and I had one killed by a "Jap" (Oriental graded to AG). This Jap cock was one of the most worthless birds you could ever see, he wasn't game, he wasn't friendly, he wasn't big enough to want to really eat, he wasn't that pretty, etc. But he was smart enough to pull the other cock out to the end of the tie where he couldn't get hit and then he just started working on the other birds head until he killed him (probably took hours, but we weren't home or it happened early in the morning before anyone woke up if I remember correctly)...
So, we penned the Jap up, dad ended up giving him to a friend.. The friend took him home and the cock got loose or something before he could put him in a pen (as I mentioned, not friendly. About as batty of a bird as you will ever see, except junglefowl. He wasn't quite that bad); the cock ended up running the yard and wouldn't face any of the roosters in pens, on tie, nothing.. He just ran off into the woods and wouldn't come near anyone or into the yard because of the other cocks. My dads friend ended up just walking out into the woods and taking care of him with a rifle I believe..
Granted the cock didn't face currently, but with non-game stock they are the flakiest birds I've ever seen. One day they're scared of everything, the next they'll pick at things through wire/cocks out at the edge of the tie.. So like I said, you
can let other birds than game free range while others are on tie. But it can cause issues, you have to really watch the birds; like my Leghorns and Kraienköppe, right now at about 6 months old.. They will face a cock on tie to a degree, they're still too scared to jump him usually but they do face him up until the moment he grabs ahold of them and ends up running them out of his territory.
I watched the Kraienköppe and Leghorns fight each other (not long, maybe a minute or so max as Leghorns don't typically fight long) and then they turn around and seems like the same ones are back at it again in a day or two... At least games are smart enough to know "He's the boss" and leave him alone until they come of age for the most part.
God bless,
