Hi i have 3 male pigs. Charlie, Gizmo and Chewy. Literally 1 year ago, i bought 2 pigs Charlie and Gizmo. I used a midwest cage. They were fine but sometimes fight. Well a few months later i bought chewy. I was not informed at the time and did not introduce him. I just put him in the cage. Later Charlie and Gizmo started fighting. I separated Chewy from them but they kept on fighting till blood. Now i have Chewy and Gizmo in same cage and charlie alone. I want them together, please help.
