Thanks for the replies. I'm still in the planning stages yet, so no real world problems to deal with. My plan was to generally band at birth if they are clearly going to market. But then I though, what if I have one that looks like a good prospect?
At weaning, I need to pull all the calves off the cows into a sepparate herd. (By the way, how long before they can be put back together withouth them starting to nurse again? a month or two?) But if I need to bull the bull calf (calves?) into a sepparate group, that means I need another pasture for him. He's probably not going to be happy by himself. So, another question. If I do have a good prospect someday, and I need to sepperate him from the cows, would he be ok with the bull if I keep them together after weaning? Or would they fight, even with him being immature?
