Good - I am certain they will be ok. My girls often disappear into the goat field and brush my big BT girl in particular, they (goats and girls) love it.
I found that when I bought my first two goats (nanny and her female kid) they were shouting all the time... then goat No 3 arrived and peace and calm was restored... don't know if that's common, but all of mine came from quite big herds, so maybe just what they were used to... (and goats are very good at getting your attention!)
