Thank you so many for thoughts, all rather bad news for poor Pontus though.!
One thing in his favour is that as an Ouessant ram he is so small I easily pick him up and demonstrate whose the boss. Against this is that I have met a family who like mutton, and so the date is set. As we keep sheep for fun, nothing more, we really do not need a ram, and so with your advice and experiences it is clear what is best to do.
I might keep a little joint for Easter lunch (if I can persuade my family that Pontus might be yummy!)
