I bought a beautiful full grown male silver pheasant this weekend. I will not be breeding this guy, do to the fact that he has a couple of twisted toes so he will be in a pen by himself. Not to mention that I have enough birds but have always wanted one. My question is what size pen could I put him in? I have a open pen that is @ 9'L x 8'W x 8'H that is attached right next to my golden pen and I was hoping that, that would be enough space to put him in. I really do not want to build another pen if I do not have to. I know bigger is better but since he will be by himself is this enough room for him with out being cruel?
