Just locked him in his box Mick and let him out when I was able to stop in the loft for a wee while, if he started his nonsense he was boxed up again. After a wee while he seemed to get the message and was no more bother, he did rear cracking healthy YBs. He was a yearling then. I dont think I would go through the same now unless I knew the doo was worth it. Too much hassle really.
