Last year we calved 60 head heifers we bought at the salebarn. Didn't have any trouble with them. Just had 2 heifers that wouldn't claim their so we bottle fed them The wife and kids think that is fun. I didn't sell them going to give them another chance? If they mess up this time they get the axe. When we graft , we skin the dead calf put the hide on the graft, have the cow in the pen stick the graft in with its new mom and their in love. The trick is if you skin the dead calf in the mouring don't do the graft till evening. Get the calf good and hungry. If we have any cripple cows we graft their calves on a good cow that has lost a calf.
