I have 5 jills and 2 hobs, one hob has nuts that work, the other is snipped. I keep the hobs apart all the time, the only time they see the jills are when the snipped hob sees the jills to cover them, or if I need a couple of kits, in goes the unsnipped hob, doesn't seem to bother them living alone, and they are playfull enough when they are out, or battering round in the wheel, different strokes for different folks.
