What medicine did your vet give you? Is this vet a large animal vet that knows about goats?
Since you've only had them for 2 weeks I'm willing to bet that the stress of coming to a new home is a big factor in their diarreah.
You have 3, right? 2 boers and 1 Togg?
Here's my suggestion - mind you as I mentioned in your other thread everyone has a different way of doing things, mine could be right for me but not for you. You'll need to assess your situation and do what you think will work for them.
I'd keep them off grain. No grain at all until they've formed solid poops.
I'd give them the scour halt as Broody's suggested. You'll need a big syring to do so and they won't like you for it, but it really will help.
If they're being agressive, tie them up or put them in a milking stanchion (if you have one). If you just tie them up be sure they don't choke themselves, though. They're probably scared of you and even more so since you're now shoving meds down their throats.
If you can get a stool sample and bring it to the vet, that's the best choice. If not, you can take a stab in the dark and treat them with a different dewormer than you've already used. It's possible that if they have worms they have a strain that is resistant to the ivomec. You can give them safeguard (also known as panacure) and dose them at 3x the lable recommendation. That dewormer is actually made for goats so the instructions are right on the label. Just make sure that you give them 3x the suggested amount since most worms are resistant to safeguard now. Once you dose them with safeguard, see if they are better. If not, treat them for coccidia with DiMethox or Sulmet. I use the 12.5% DiMethox and treat at 1cc / 5# for 10 days - this is what my vet recommended after I brougt in some stool samples. You may not need to be that extreme, though, but my girls were showing a high fecal count of coccidia so we needed to be agressive.
Get them some minerals ASAP. If you can't get the loose minerals, a mineral block will do. NOT a salt block.
Check the color of their eye lids. Google FAMACHA chart and compare your goat's eye lids to that chart. If they are anemic due to worms, their eye lids will be very pale. I give Red Cell, which can be found in the horse section of most feed stores at a rate of 1cc / 10# for 5 days straight. If their lids are only slightly pink, you can ease up on the dosage.
Again, this is what I'D do - other's suggestions will vary so you should take in all advise and decide what you think would work.
