I really like some of the Proud Jazz calves. Chiller is supposed to be calving ease, but I have never had any of my own, like the ones I have seen. Tonic works well, better on some lines than others. TM Gus seems to be making some pretty good calves, talk with Stumpy on here, he will be able to fill you in on the particulars. Yes, it is harder to find a shorthorn with a low BW that will still throw you a "show heifer", but it can be done, it does happen.
