I have 3 fused vertebrae thanks to a 'pet' ram castrated in adulthood by the rescue place I used to work for.
He was hideous and spoilt. 'oh he thinks he's a dog' was all you would hear if you mentioned his aggression.

he knocked me into the corner of the barn and kept coming. i swear he would have killed me if a co worker hadn't seen it happen and drove him out with the pitchfork.
I dont take the chance now, and never ever trust any ram, castrated or not.
