My five year old boer whether is a cranky old fart. He's big and has horns that he likes to use if you invade his space. He'd be eaten if he belonged to anyone else. I can't do that. My question is: how do I worm him? I've had him since he was weaned and has been a wild one from the start. I used Ivermectin orally on him up until about a year ago when he got mean. Any ideas how to get a wormer down his throat? He's not the kind of goat anyone can man handle. He needs to be wormed. Has anyone had any luck with the grain wormers? I can brush him and feed him treats, but if I try to catch him he rears and tries to head butt me. Uggg.
