Agree with Uncle Matt. Seen similar conduct many, many times. You hunt long enough you'll see some more "weird" conduct.

Have seen a big buck trying to gore the bigger buck that I had just dropped.

Have seen a young 6 pt. buck "nosing" a doe that I had just killed during te estrus time. Tried to roust her up. She must have been in heat. He would notgive up and pushed her all over the forest floor before I finally was able to spook him off. I did everything except fire again trying to get his attention. Yelled, whistled, barked, threw my hat at him .... eased my pack to the ground and jiggled it up and down several times before he saw it and ran off.

I have had deer scatter like a busted covey of quail at my rifle shot ... and other times have had 'em pay no attention to the shot other than raise their head for a moment.

Lots of usual and "unusual" conduct. Part of what makes hunting such fun for me.
