Chicken fights!

[BlackLotus44]

My two, three months old Sagittas and one three month old Amercauna keep pecking, and snapping at each other. They share the same coop and feed bowl. I feed them just perfect, but is there a way to cease their fighting behavior?

Wring two of their necks or else provide more or bigger food bowls
