Hello,

For the last few weeks i have been trying to bond my two rabbits Rolo and Archie. 

This came about, after Archie’s partner Biscuit Died suddenly on christmas eve. He didn’t seem to struggle too badly with her loss, But i figured after a few months it would be good if i could bond him with my single female Rolo. Originally they were a trio but biscuit and rolo began fighting (Rolo had started humping Biscuit but was submissive to Archie) and i had to separate as it became obvious that Archie and Biscuit had become a solid pair and booted rolo from the group (Archie began attacking her whenever he saw her). 

The problem i am having with the bonding though, is that Rolo appears pretty submissive, and interested in Archie. She will occasionally lower her head to ask to be groomed, but otherwise has not shown any other dominance or aggression to Archie. However, if she moves, or even goes near him, he charges her, nips her and makes a weird grunting noise that he does to me when he is grumpy. Because Rolo doesn’t seem to even be contesting him when he nips, i’m not sure how to proceed, he is a lot bigger than her and im worried he is going to hurt her if he keeps biting her all the time.
