jills and hob both have their place, I use the jill first then put the hob in if theres a stubborn rabbit, or just to check over the burrow ( I find the hob to be thorough) or if a bigger burrow I work the two together. you'll find your own way to work them.
for feeding, my ferrets always have food available in the hutch. so they eat whenever they please. I don't feel the need for that starving or making sure their full before hunting shite. I just take water for them when were out.
