White Eared, mikado, Impeyan, Koklass

I'm thinking about adding these four types of pheasants to my collection. I have already have or had Goldens, amherst, ringnecks, elliots, Temmincks tragopans. I was wondering if my pens were big enough which of these birds could share a pen. Plus I was wondering if someone could tell me a little bit more about koklass, and white eared pheasants. Thanks

White eared dig like a banshee. They are large pheasants, and I keep mine in thier own large pen.
