The vet gave me the impression that it’s quite a big thing (actually two big things
) in a three month old lamb, and he’d prefer I organised it earlier.
My situation was choosing castration by vet as I had a few I wasn’t able to ring within the first week. Perhaps I’d have had a different reaction if it had just been a single tup, and clearly an unusual situation. In later years we burdizzoed ourselves and found that perfectly satisfactory. (Ex-BH was very experienced with the burdizzo; it’s not a suitable option otherwise.)
As to the sparring : it is proper testosterone-fuelled fighting, is it, not just sparring over food resources with spring in the air? I ask because some of my non-pregnant adult sheep (wethers and unbred ewes) have been doing a bit of head butting in recent weeks, but nothing serious.
