Ours have had that too MGM. Think we picked it up at Angus show, as the males got it after there. Then it moved on to the goatlings, milkers. Female kids got it last, and they are only just getting past it. Then we managed to pass it on to my sisters goats....
It's passed over them all, snotty noses, a couple have had coughs, but it does just seem to be a cold.
Keep an eye on them, because I guess just like us humans, one of them could get a secondary infection from the cold.
