DO NOT use Bourbon Street on heifers! He is advertised as calving ease. I had 3 heifers bred to him last year. Got 2 bulls and a heifer. First bull I got out with the jack 90 lbs and dead. Second was the heifer 80 lbs and she's ok. Third one was a bull c section 100 lbs and died the next day. When these guys say use proven calving ease you listen.

NO BULL IS FOOLPROOF BUT-Mr Colt is proven and i 80 is proven-BOTH ON SHORTHORNS Colt will produce a showy one in more instances than anything listed-and is just as good a bet for CE However-his calves can come VERY small-It looks like your heifer has enough grow that it would work out I saw the first ten or so at a young age at Wills place He said a commercial guy paid way over market for all the heifers he would sell O0

Have had experience with No Worries and I-80 both are highly recommended for ease of calving and also quality calves.The heifer is as important as the bull used and heifers that have good condition have had exercise and are built right to be a females.Small framed, shorter bodied,overly fat heifers that are heavily muscled with a small pelvic area can  be trouble Heifers younger than 24 months in many cases are not as well developed.Many ranchers rely on pelvic measurements when keeping replacement heifers.Actually calves under 80#s are plenty for most heifers. A live calf is the main goal .

Cowpoke you just hit the nail on the head. I breed hers for costumers a long time and I had to quit. I'd breed to only bulls that I used myself and constantly get complaints about pulling calves or C-sections. I'd run over and look at their two year olds and they were over fat small framed cattle usually in a feedlot setting. When I breed those cattle I thought they looked good then what I think would happen is 60 days out they would pen those cattle and pour the feed to them. The last year I had 50 or so first timers and never pulled a calve out of a proven Angus bull. One guy had20-30 head  I used the same bull and he pulled 90% of them. That two year old needs to be handled with care not to fat and not to thin. As far as the bulls you listed I-80 has been fault free for us.
