The other day i was in another pen and out of the corner of my eye i saw my large male doing some unusual behavior. I looked closer and he was in front of a large female on his very very front tippy toes at a full stretch. I was careful not to make any sudden moves and watched for a couple minutes as he made what seemed to me to be a display and then plopped on the ground and grazed as the female showed no change. So i went inside and came outside maybe 10 min. later and they were in the act. Has anybody seen this or similar behavior?
