The short answer is NO!
Do you want the long one? Well......for starters its cruel as the animal cannot get away from weather or danger. He could, if not supervised all the time hang himself or break his leg. It will make any bad temper worse not better.........I could rant on but I wont!
What you need to do is sort out your sheep keeping facilities! First of all so long as there is enough grass etc a ram kept in with a flock will not hurt the lambs...... unless the ram lambs are uncastrated and challenge him when he might knock them about. You are in more danger of him serving his daughters when they start to cycle in about August..........and no they do not have moral issues!
Ram lambs should be castrated unless going for meat before autumn or being kept for breeding, the sweet little ram lambs will otherwise become a gang of testosterone filled hoodies!!!
Your ram needs company if kept apart from the ewes and to that end get hold of a castrated wether for company they will fight a bit to start with and then settle down like a couple of old lads!
To keep him in check you need to make sure he respects you, more people are killed by rams than by bulls! ALWAYS take a large piece of thin plastic pipe with you, the sort they use for water pipes etc. If he attacks swing it with force at his front legs NEVER his head. If you whack a ram around the head he will attack more as he will take it as a direct threat.....fighting rams bash heads!
Never turn your back on him, never pet him or stroke or scratch him behind the ear etc nor feed him by hand. Always ignore a ram unless it is to be caught for something like worming or foot trimming.
If he is really foul, and you really either cannot stand him or don't need his services, DO NOT pass him on to someone else, make him in to sausages or something.
If you need more help please ask I have had sheep for over 25 years
