Hi, I found my 3 month old 88%boer wether, dead in his pen this morning. He had CD/T and booster, he had pellet dewormer a few weeks ago. I had added a pinch (literally) of Calf Manna, to a handful of COB. The other goats might have injured him? -- he was acting slow and sluggish the day before, and i had found him laying down on his side, flailing and screaming, i set him back up and he had a normal temp, gave him Nutri Drench, and he walked right over to his momma. any ideas on what this could be?
