1 of our 4 expectant heifers dropped earlier today. The weather was a wet 40 degrees or so, and we got there too late. The calf(at a glance) and mother looked well, but when I noticed she was down at the north end away from the others and we got to the hour or so old calf, it was dead. Mom was standing over her and licking afterbirth but to no avail. It doesn't appear to have ever of stood up. Any ideas as to what we may have done or could have done? IE; should we have penned the mother up due to the colder conditions, feeding inconsistencies, etc.
