If he's just fence-bashing when you feed the ewes, would it be possible to give him and his mate some feed first? You can get ones that are less nutritious, and just give them a handful each to keep them quiet...
If he's getting generally stroppy, then you can choose whether to get rid of him (or castrate him) now or wait until he's really hurt someone
.
If you aren't planning to use him this autumn, have you thought about how you will contain him - and protect yourselves from his frustration - come tupping time this year? If the ewes are within pheromone distance, he's going to be one stroppy boy...
(You seemed to be wanting some arguments to put in front of hubby. These do?
