I know this is an older thread, but recently I have been intrigued and want to try a BM bull on my Red & Black Angus cows and replacement heifers. I have read a lot about the advantages that can come from the cross, as many members here have stated as well. My only concern is I spend a long time getting rid of horns and haven't had to dehorn a calf in ages. However, most purebred BM bulls that I have access to have horns. Even if the cows are polled won't I start having a percentage of calves with horns?
