The first thing that I wanted was a goat, love them, adorable...grew up on farm, loved it... then you have milking at scheduled time, breeding to continue milking ability, milking 2 times a day, milking 2 times a day...
I would assume that goats like cows and sheep get tangled in wire, need added security because bear and dogs- neighbors dogs, like to kill them and eat. Then you have milk fever, problem births, mastitis, and bloat.
The vet bills and if it gets loose and eats your neighbors garden, there will be some hate in your neighborhood! lol.
I am sorry, most of you goat folks do not have all these issues, but it is a reality to owning any milking animal.
Oh, forgot that you have to buy or turn a field into hay, grain and wormer,Vite's, and with cattle they tend to step on their teats and when they do, it ain't pretty! Such a horrible thing.
Good luck on your choice!
