Sorry the issues and troubles continue... I hope you can figure out what has caused this turn of "luck".... Hope you're able to save the lambs and ewes.
We had something similar last year with a quad. His heart rate was crazy high and and was breathing very rapid. Gave BoSe but didn't think he'd make it through the night.Wendy, one of the new bottle babies, is struggling. She seemed ok when we picked her up, but a little while later, she started having issues. She has a really high heart rate and I suspect White Muscle Disease. She's received BoSe, but it's hard to tell if it's helping or not yet.
Since it's affecting her heart, chances aren't good that she'll recover.
