As a Gamefowl breeder myself, I usually raise my Birds up early spring and dub them in the middle of winter (December, January), Since the cold weather helps stop the blood much faster and Roosters aren't pumping with testosterone, I dub with surgical scissors but I have used a razor blade once, Which I only recommend using a razor blade if you've dubbed before, Its not as easy, And from what I can tell if you keep the Bird calm in the process it doesn't seem to hurt them to bad or at all, My Birds never flinch or freak out when I do so, Most of the blood that comes out is the blood that was already in the comb and wattles, The only part my Birds tend to somewhat squirm is when I'm doing the earlobes, Which they still don't scream or cause a scene, They just simply shake they're head a bit, Its easier than it looks but please do a lot of research before you dub, You can mess up easily if you cut the wrong bit but I suggest doing the earlobes first, Then the wattles, Then the comb, When dubbing the wattles you want to cut along the feather line, If you cut into the feather line your cutting into they're neck and you don't want to do that, The comb is easy to dub, If your dubbing for show then cut the back of the comb off and then from the beak to the back of the comb, They have a natural line you wanna follow, Make sure the back is well rounded, If your dubbing and your not dubbing for show, Just for frostbite purposes then I recommend dubbing to the skull like they do with Modern Games, Its easier to do and lessens the risk of frostbite compared to a show dubbed Bird which still has some comb left, With the bleeding I'll take some flour or bleedstop and dab it onto where they are bleeding, Some Birds don't bleed as much as others so if hes not bleeding much only do a little, If hes bleeding a lot I recommend doing as much as you can, Good luck with your Birds
