Well, how important is it to you that you keep this piece of schitzen animal?
Last week a neighbours daughter was placed in the hospital by a young bull - ran her down in the field before she could get to the truck. Animal was only 8 months old and showed NO previous signs of aggression.
17 year old girl in hospital - beat up but will live.
If you can catch it to cut it - cut him - banding takes too long - cut is faster - and if you have a place you can force it to live where there is no danger to you or to your family - you can take the chance.
No matter how wonderful this animal may be he will take a LONG time to settle down - and that is IF HE SETTLES down.
Options for you - shoot him and eat him - sell him - but not as a breeder - no discussion here as far as I am concerned - he is a piece of schitzen and needs to be treated as such.
I am surprized you would think you need to ask - but you now have my opinion.
DO NOT PASS THIS PROBLEM ON TO SOMEONE ELSE!!
If you sell him - mark him as aggressive. Buyer needs to know and seller has a moral obligation to speak up.
Up to you.
