Thanks Taurus! To be honest I'm not 100% sure how the big heifer or brindle calf are bred since I just bought them this spring. The big heifer is out of a angus cow that I bought as well and I believe out of a brahma cross bull. I'm pretty sure the same bull sired the brindle calf as well. The man I bought this group from had 3 bulls running with a 100 cows so it's impossible to know for sure. I'm excited about the heifer and think she will make a great cow!
Whatever the breed the bulls are, he left you a nice heifer and a nice calf. I like that black Hereford cow, I hasn't seen a high quality black hereford in long time.
