I have 3 toms and 2 hens cooped up in a large stall and run, I realize it is mating season and the Toms are getting aggressive towards each other and need to be separated, not a problem. My concern is that one of the large toms comes toward me when my back is turned and not quite but acts like he wants to peck at me, which he actually did once. I sort of shrugged it off at first but today he came closer and faster and when I checked the nesting boxes he followed me like he wanted to corner me. When I turned and stood up he backed off a couple of feet and started walking toward me again. I'm thinking he wants to challenge me. That being said, when approaching a tom and he struts and drums with his wings down is that a threat or just a tom wanting to be friendly? What are the signs of aggression? Any advice?
