Vic is correct on the orneryness of the russians, especially males. I tried to temporarily house a larger redfoot with my pair of russians in a large outdoor pen. The male russian continuously harassed the larger redfoot. They were split up immediately. I could see he would have inflicted major damage on the redfoot if given the opportunity. Luckily, both the species you are interested in are relatively small and will not require huge enclosures indoors or outdoors.

Best of luck.
