Could be dietary...green tinted runs is from too much grain/graze/wet graze...
did he get into anyones feed? Introduced to new pasture?
Could be worms...dark brown to black...
have a fecal done to see if your wormer worked...check his lower inner eye lids for color..should be deep pink to red
Take his temp..shouldbe 101.5-103.5

Stop all grain...give pepto ..give cd antitoxin...offer electrolytes to keep him hydrated...here is a great recipe
Homemade Electrolytes
A half gallon of hot water
2-6 Tablespoons of Unsulphured Blackstrap Molasses or what you have on hand or honey
1-2 Tablespoons of Either Sea Salt, Epsom Salt, Baking Soda or Table Salt.
1 cup of Apple Cider Vinegar


Mix well and drench or let them drink it.

Stress can cause many things and certainly the runs...but I wouldnt hang my hat on that hook alone...

Ivomec is 1 cc per 40 pounds so 2 cc was good for 80# goats..I give it Sub Q never IM which is very painful...If worms are heavy I do it 3 times 10 days a part then once more in 30 days...
could be the low wormer dose didnt do the trick and he still has a worm issue...I would have that fecal done just to be sure....
