I responded on FB... it's a welfare/effort issue mainly. 2 weeks is pretty common in cow farms to wait for improvement, because at some point they are worse off for being down and they have very high demands for care. It can be done, but the goats' welfare should be considered - she'll require being forced to move several times per day, on superb clean bedding, have all her needs catered to for potentially months. She may never fully recover and she may not be as able to compete with others, have trouble with pregnancies/breeding etc.
IMO on a dairy, the animal may or may not be worth the effort of the healing process and possible long term effects. That's your friends' call. Maybe they're home/willing enough to do the intensive care - many larger herds would opt to cull instead of giving intensive care to one animal that in the grand scheme, isn't worth the effort. But, that is something only your friend can decide with her personal relationship with that animal, her history of kidding problems (was it severe dystocia that caused the neuro problems?), her genetic value, wether or not she has a good replacement in the herd (If out of her triplets you have 2 daughters to replace their dam with... she may opt to keep the daughters instead)...
