They all need to be de-wormed ASAP with Safeguard liquid for goats or Safeguard Paste for horses, Dose to treat the cecal worm is 0.23ml per pound and repeat in ten days. If any ot the other look sick you should treat them with metronidazole, whicj is sold as:
Meditrich - 100mg tablets
Fish-Zole - 250mg tablets
Aqua-zole - 250mg tablets
Flagyl - 250mg tablets
API General Cure powder - 250mg (plus 75mg praziquantel)
The first four listed are tablets and easier to give, so that's what I think you should buy. If others look sick, get the powder. Powder is very expensive and hard to give, so don't get it unless you have other that look sick. Make sense?
