Housing fixed rabbits next to unfixed rabbits

[Lagomorphian]

Alright, basically I have three bunnies, two males and one female, all fixed. They have all finally started to settle down in terms of hormones and I am trying to bond them, which has been going pretty well so far. However, recently I have offered to give a temporary home to a friend's bunny over the summer, doing so without knowing that the bunny was unfixed. Now that I've already offered, I wanted to know if housing this bunny in the same room as my other three would affect their behaviors in any sort of way, as I have previously heard that fixed bunnies can "feed" off of the hormones of nearby unfixed bunnies and exhibit their old, hormonal behaviors again. Anyway, thanks for your time.
