OUCH -- on the finger. Comfrey does work very well for most such injuries. I put some leaves into olive oil, close the canning jar & set it in the hot sun for several days, shake it each day. Soon you have an ointment. It works. Such a thing is great once the compress can come off.
My goats are taken to different fields for a "day trip" to browse, rest their regular field and help keep my fields cleaned up (weeds?). I have a driveway sized path down the center of my farm, pastures on each side, which allows me to open & close gates to make moves.
When I go to their field and open their gate they follow me to the next, and the next....they run down the lane and enter at the opened gate to graze. Looks like the Pied Piper, LOL. But it sure makes life easier to catch them, move them, work them. Goats are VERY smart and love routine.
Same with milking -- don't go out of order!
