150 goats and only one has been bit, and im willing to bet that you havnt gone around and killed off all the hots that are on or near your land?
you know animals are not as dumb as you may think they are, birds dont eat some butterflies cuz they know them to be poisonous and rattlesnakes dont have rattles because of humans its for all animals and it seems to have worked so far. nature works till we screw it up.
how man ranchers live in areas where there are venomous snakes and have thousands of livestock and lose few to none due to snake bites?
i know my uncle has ran several cattle farms for 40+ years and has never said anything about losing a animal to a snake bite and believe me when i say if it happened you would hear about it cuz he never stops talking about his cattle.
