I have two female emu(2years old) and two males(18 years old) Usually it's peace on earth around this farm. Recently, my one female emu turned into a jerk. She is being aggressive to my males, pushing them and chest bumping them and snapping at them. My older males are super calm and not happy about this going on. She is even worse with my other female emu. She really goes after my other female to the point where she made her bleed and damaged her wing. I had to segregate my nice female emu from the mean one. Neither of the females lay eggs yet. And I thought maybe the aggressive one may start lay to soon. Any advice so I can bring peace back to this farm? Thanks
