Our two big Anglo Nubian boys hated having their feet trimmed when they arrived, and they were nervous anyway, so it was a nightmare. Plus their hooves seem to grow long very quick, which made things worse. But they have improved with time.
I would suggest you need help the first time, to see how the goats are. One to hold, one to trim. No matter how tame, some object strongly to feet trimming, and will be quite difficult to hold still. Any which are not easy to trim, we push up against a wall, gate, or something solid, and pin them against it, until we have a foot in the air. Try to be as quick as you can, as they will not want to stand long. Ignore any yelling and keep going - stop if you draw blood, as you have cut too much. We always spray the hooves after they have been clipped - purple spray, footmaster.
Good luck!!
