I have experienced something similar too. My dad's current herd is mostly black angus cross cows, and when I turned my 4 herefords out with them, I noticed that they always stay together. I'd say it's probably because I bought them all from the same guy, but it's just funny that when you go out to check them, they will be mingling with the black cows, but you will always find the 4 herefords within 100 yds of each other. I've got a couple more to turn out in December after I get them AI'd. They came from different herds all together, I'll let you know if they mingle with the blacks or stick together with the other 4 herfs. Racist cows, who'd of thunk it!! :lol: :lol:
