Agreed it would've been a better idea to get 2 jills and 1 hob but as for two hobs fighting at 5 months and needing seperate cages,
not in my experience.
mine started ragging / wrestling at 5 1/2 to 6 months and ones back was a right mess, i meant separate cages eventually not at that age, and i agree with Ideation, occasionally hobs can be housed together but its rare in my experience.
