Because when you catch the issue later on, about a week or two later the born is pretty attached/big I guess you could say so you would have to burn longer to make them not grow any more. Or so I've read remember I don't reburn lol I just deal with the scurs which except for 2 does has always been these tiny little things. But I think my alpine boy should be reburned. My goodness he had HUGE horns already at a week old and I kinda knew I wasn't going to get them just right but if I can get my hands on him I'll show you what I mean. I know where he's going to end up so for sure no point in reburning him. He won't have sharp little horns so I won't loose the bid of the feed lot type guy so it is what it is.
