I'm not sure where to start. I've had 4 goats die on me in the last week. One 4 year old nubian doe, one 9 month old boer, one 2 year old boer/nubian, and one 3 month old boer/nubian. The 4 year old nubian and 2 year old boer/nubian were skinny but not alarmingly since they were nursing. The 3 month old doe belonged to the nubian. I now have three 3 month old orphans (at least until they die) one billy from the nubian and two does from the boer/nubian. For a timeline reference, all ate well today. Tomorrow acted off, but laid around chewing their cud and browsing in the pasture. Found dead on third day. No diarrehea, and I've been giving them ivomectin 1.87% horse paste wormer when needed, and free choice minerals and salt. Not sure if it matters, but the weather did turn between hot and humid and cooler and rainy during this time. There is plenty of pasture, and I give some sweet feed every day. I'm out of ideas and running out of goats.
