I went out this morning after dropping my son at school, so I wasn't out at first light. Thought I would just slip around till about noon. I hadn't gotten but about 200 yds in when two does blasted by me. I knew what that was all about. Sure enough, a buck came not a minute behind them. Problem was, he took a detour and came behind me crossing my path. When he caught my trail he suddenly stopped and started backing out. He presented a decent 20 yd shot, but it happened so fast that I choked and shot over him.
So to answer the question, yes they are chasing, at least to some degree. Saw a young one a week ago doing almost the same thing.
