My rooster and one of my hens were fighting each other this afternoon. Why were they fighting? Belle (hen) was really nasty with him then she went to my broody Mama with 2 week old chicks and fought her too, Lance (rooster) came over to break it up and then Belle turned around and started fighting Lance again, he then had to get nasty with her then he mounted her. Why was she fighting Lance? Any and all answers or advice are greatly appreciated. Thank you.
