When it gets a little older, you will have to clip its wings because both breeds are very flighty and are known to roost in trees. I have a dutch bantam and she flew over my 8 foot tall coop.
The only bird that Murray McMurray sells that seems to fit its appearance (leg color, feather color and pattern, etc.) is a Black Breasted Red Game pullet.
I had one that looked like that. When it was a chick it was all black with a light reddish head. feathered out the same and ended up being what looked like a black sex link.
