The main thing to keep in mind when you have a goat with diarrhea is that there's no way to get a definitive diagnosis w/out a fecal.
There many causes for diarrhea, some life-threatening, some merely mild stomach upset (like too much green pasture).
It can be dangerous to assume the cause of your goat's diarrhea is the same as someone else's, and / or that the treatment they have success with will work for your goat.
Location, diet, parasite loads, age, overall health / condition and type of parasites...ALL can have an effect.
Any goat who's not pooping 'berries' here would get her temp taken, eyelids checked for anemia, and an overall visual check up. I would take into account any possible feed changes (lush pasture, new hay, etc.)
I would then give them some probiotic paste, and if they have pale lids, they'd be dewormed w/ valbazen if they're not pregnant...ivomec or safeguard if they are.
If they have diarrhea for more than a day, a fecal sample would go to the vet...
If a kid has diarrhea, they get a fecal ASAP, unless I know a possible cause (coccidia in older kids, e coli in younger ones, worms, new feed, etc.)....kids can become dehydrated and die amazingly quickly.
It is fairly common at our farm for a heavy-bred doe to have clumpy poop. But diarrhea is never 'normal', and warrants some investigation.
