I'd find him a companion too.
The tup lamb we bought last year has become overly 'friendly' with us as a result of having no-one else in with him. And at 80+kg now, that's become less than funny to the point that we're selling him a year early cos he's so hard to handle. Lovely, yon side of a fence, but dangerous now when I'm in with him.
The farmer down the road said he thought it was having no-one else in with him, although he was often just a stock fence away from the girls.
