Hi Everyone, we recently lost Blackie our ewe to copper poisoning and it's been heartbreaking. She had 400x the amount and her kidneys were huge and discolored. Vet said it's been the first time in about 15 years he has seen this and we are just bewildered. Not sure where or how she ingested it. She's in with 2 other ewes and they have not come down sick nor have our ram or lambs. Vet said everything we're doing is right. Has anyone had a mystery like this with your sheep? I need to check with the vet, but is it possible to have other flock members' copper levels checked? We also need to have our feed tested. If this happens again, I don't know what I'll do. Thanks!
