I hope that we get a new area fenced for just the boys soon, but they both became mature at the same time and are now forever head butting each other until their heads bleed. Is this normal? I thought you could keep two bucks together that were raised together their whole life. They are 6 months old. We currently have all the females in one pen and the two bucks in another. The only thing I can figure is we sent one buck off to breed for our neighbors. He was gone a month. Now that he is back, the trouble has started. We thought about selling one of the bucks and then the one we keep will be the herd sire as well as the only buck on the property. Maybe that would calm him down??
