Ewe delivered today, but it looked weird, so I called the vet and turns out placenta was birthed first. First lamb was a big black ram, second a tiny black ewe and third a white ewe. The first took a breath but gave up and died, second was already gone and the third seemed to be the stronger but she also passed despite of colostrum and warmth and a loving mother.
The ewe is missing her babies but otherwise fine.
