i'm not sure what kind they are. Hopefully a pheasant expert will come along and know. Great picture, they look super healthy. If they're eating, drinking, and pooping, you must be doing it right!
Oh gosh, i don't know what to tell you but wanted to give your post a bump. Is there a wildlife rescue place in your town that could give you pointers? Perhaps the local SPCA could provide a link. Failing that, you may want to check with some hatcheries that sell pheasants to find out about...
