all animals are Inividuals mate, you need to keep and eye on yours, and see how they react, someone could have hob and jills that live together without a hitch, you do the same, and have world war two on your hands,
once your hob is snipped and as kay suggests, a couple of months down the line, introduce them, if your jills are in season, he'll bring them out of it,
