Hi, I just recently purchased 5 hiefers. I was told they had all had one calf and were pregnant with second calves. They weigh between 1100-1200 lbs. When I purchased them they were running with a bull. The guy I bought them from told me they were ready to calve any day. That was 30 days ago. I don't have a holding pen yet, so I cannot contain them. Can you viusally tell if these cows are pregnant. They have small milk bags, no leakage yet and no vaginal discharge.
