Haven't had goats for years. When we did we vaccinated for pneumonia (yearly booster), clostridium C and D, tetanus, and maybe something else on an annual basis. I honestly don't know if this is the same pneumonia that wild sheep and goats get, but its a common domestic goat killer.
We also wormed them about every three months or so.
You can buy the vaccines at your local feed store and maybe the vet for some. Helps to have friends with goats cause you have to buy a bottle of each and you wont use much of it for a few pack goats. I'd buy the bottles and then shoot up everyone's goats a knew of. The Feed store has the syringes as well.
We didn't pack in any food other than some emergency alfalfa pellets (weed free requirement). Also packed in Epson salt, pepto bismal, some would care stuff, and their water resistant blankets.
We high lined our goats at camp when hunting. Hard to hunt with them cause they will walk all over all around you, Makes shooting and glassing difficult. We'd let them off mid day to feed and then in the evening to feed. We'd move them around so they didn't scalp the brush near camp. They would clear the highline location, so you had to keep that in mind when looking for a location.
Our goats were either on the high line or within 50 yards of us. They weren't rubbing noses with wild deer, sheep, or goats.
