Two days ago when I checked on my goats, I found our 6mo old doe Roxy in distress. She was very lethargic, couldn't really walk or move. I gave her electrolytes and yesterday morning my vet gave me a dose of nuflor and b12/steroids. She seems fine, but yesterday I went to check on the others...my first goat was in distress and one of my nannies. I hydrated them. Also, I gave nuflor. A fellow goat friend gave me Banamine to give them. This morning our little goat was dead. No diarrhea, fever, or anything...I'm clueless! Any ideas???
