I have a brangus angus cross that is due this week. 2nd calf heifer. Her first calf was a success. She has been bagging up for about 2 weeks and has been having clear discharge for about a week which I see all the time. I have been watching to see the bones on her legs widen and she looks like she is ready. She had a bloody discharge "string" hanging out this morning with no plug, and is acting normal. Never seen blood without a plug before. She ran a 104 fever 3 months ago so I was concerned about her aborting but we palpated a few weeks later and the vet said everything was normal. Any thoughts?
