When photographing non-voice-controllable subjects, the potential of capturing all subjects in the frame with good body positions decreases exponentially with the number of subjects.
With a single subject, capturing a good body position is sometimes challenging but often not too difficult to accomplish. Add a second subject and the challenge doubles and it doubles again when a third subject is in the frame. While not every subject in the frame is required to have the ideal pose, it certainly helps when all have one.
I had been hanging with these big boys for several minutes. When enough distance separated them, it was not too hard to find individual subject poses worth photographing. When both bulls were in the frame, good opportunities became scarce with the second bull often becoming a distraction to the first.
Photographing groups of animals includes increased challenge, but that challenge serves to make the rewards of success higher.
