Our Nubian goat takes about a half hour of walking down to the barn, feeding, and milking daily. Night time is only a brief feeding (if winter) and lock up, maybe 10 minutes. But that's 1, not 24. For just the milk, the labor is worth it for us. Farmers style goat cheese is fairly painless to make with maybe an hour or so actual handling time total for a 5 lb block.
Yeah, my friend certainly loves her goats, and the entire lifestyle around them. Her day job is research with an agricultural institute and basically lives and breathes goats.
Soaping and showing seem like a labor of love.
