when we got flopsey floppy went nuts to get at her and he couldnt even see her , i wonder if jane is on she has lots of buns????
Floppy would likely be your risky rabbit in your current pair then.
Personally speaking, inside I have a pair, a trio and three singles all in 'reach' of each other (the pair is a foster pair). The pair can access any of the bunnies who are running. If the trio, or one of the singles are running, they scrap. If the other two singles are running, they don't, and don't care. When the trio could access everyone whilst running (basically meaning living in the ground floor level of the NIC cage) then they never scrapped regardless of who was out. When Sandy was there, she used to wind up every bunny and ALL would end up scrapping.
Outside i have two trios and two pairs. If they can see each other then all hell breaks lose. I have the most volatile pair up the garden, away from the others. I have two split by a soolid wooden divide, and the other pair set a small distance away, which seems to have worked. When I had two trios and a pair all in a line, and didn't realise about my groups' referred aggression being triggered by sight, I found myself with three groups of fighting rabbits all at the same time.
It's about knowing your rabbits. I could tell you, out of mine, exactly who would cause problems, and how (be it chasing, humping, full on fighting, etc). I'm just exceptionally lucky that they don't get triggered by smell!
You have to know your bunnies and work out what is best for them and how to work around any referred aggression problems and if you take on another pair, you need to be prepared that the may also have referred aggression and that you might have to make adjustments to both pairs and how you keep them and how you move between the two, in order to ensure all bunnies are safe.
