Treat him as human aggressive. I would say that right now he is testing. Before long he will attack to your face.It is funny how Big Jim is. When he sees me coming up to their area, he and the hens run to me. He will get about 5 feet from me and stares. I will carefully toss the mealworms at his feet, but he just makes this soft sound and lets the hens eat it. He takes a while before he starts eating and allows the hens to snatch the mealworms from his mouth. The time he jumped on my back, I had finished feeding them and was leaving. I turned to face him and he didn’t do anything but when I turned around, he did it again. It didn’t hurt, I was not sure what he was doing. I don’t know how I should deal with this.
