When a jills ready to be brought out of season she will not fight the hobs advances , sperate the hob from the jills & try one jill per day , if the jills not ready for his advances simply remove her from his cage
All leaving them to it acheives is sore necks , when a jills ready to be mated , the hob will simply pin her down , do the job & leave nothing more than a damp area on her neck & maybe slight reddening to the skin
You should be able to have 1 jill brought out of season in an hour or so, then pop her back in her cage, give him a day or so breather , then try one
