am in the same boat mate,i have 2 jills and one hob.the 2 jills are not in season but the hob will give them a hard time,i let my ferrets run about in garden sometimes but keep a close eye on them,the hob always trys to get the jills through the hutch bars,ill be keeping them apart till hes out of season that way i dont risk any of the 2 jills getting badly hurt.you could be lucky and he might just chuck them about but sometimes they do end up badly injured
