Well, you wouldn't be able to range at all when they are mature. As far as oeg and moderns, those aren't really gamefowl, but in name only. Now if you get someone that has bred american game to an oeg standard, you will have game issues. BTW, when buying hatchery stock, all bets are off as especially when it come to oriental games, you won't get what they claim in the first place, let alone expect them to be game. To anyone wanting to start out with gamefowl, the first thing you need to do is research thoroughly to see if you are willing to do what needs to be done to keep them. That means penning birds up where they can't get to each other, and if you have other birds running loose, you will need to have sight barriers on the pens to keep the barnyards from pen fighting the gamefowl. You also need to be prepared to pen up all your young fowl when they become of age in the same manner. Even the hens many times can not be kept together if they have been separated for any amount of time. Now, if you are willing to go that far, I would look into a reputable breeder of Asil, not a hatchery, and not eggs off ebay. You can end up with birds that are a joy to have, very calm and personable to people, and excellent broodies. If you try to cut corners on getting birds though, or on your husbandry, it will be a bad experience. Also, don't expect them to lay enough where you can eat eggs, but they do butcher up well if that is your desire. Keep in mind though, if you are going to own games, and respect the breed as it should be, you need to breed for gameness. If any of this is an issue, I would suggest maybe a good line of cornish.
