No absolutely not it will not make your goats stupid. Look up fiasco farms on google and go to their website they have distinct instructions and photos and they have mini's. I have had both. Not having horns saves sooooo much trouble getting in the fence, aggressive issues, accidents, etc. but they are harder to catch and hold. Having horns you have to be prepared for it because they will get stuck and fight and have accidents and occasionally you will get scratches and nicks from them on accident. On the bucks I have never had one without horns strictly for handling issues I just can't or couldn't control them big boys without a handle. It may be different there for you with minis. Before you did any disbudding (removing horns) I would read up and talk to people so you know what you are doing because it does need to be done correctly. And if you want disbudded goats don't try to do it to an adult it is way painfull and a major risk. If you do the babies when you first see the buds they holler a little and don't like being restrained but immediately after they are fine as soon as you let them go. It does not fry their brain unless you are cruel and hold the iron on too long or something weird like that. And burning it leaves a nice clean cauterized spot that heals real quickly and you have no fly issues. I suggest you read up and do as much research as you can before you decide. Many people have pros and cons of each.
