We have an pet American BlackBelly Ram. He is small : about 70 pounds. We also have two adult female llamas. Around 400 pounds. They have been together a month on one acre. Most of the time they get on OK but sometimes, the ram tries to butt or kick their legs. Then they spit at him + he backs off. This often seems to be when I go into the pasture or when they're fed. It looks like he's herding them away from me or their food. But sometimes he charges the llamas really fast. He bounds / bounces at them. It looks dangerous and they run. When this starts he gets put in a separate small corral for the night. Any suggestions, please on what to do? Why is he doing this? I am worried the llamas will get hurt. I don't want to keep him separate + also don't want more aminals.
