This statement makes me think they aren’t fully bonded yet:
“They share a litter box but they don’t snuggle. The trigger just seems to be submissive bun approaching dominant bun. She gets chased off and it’s all over. I am not sure they are properly bonded. On the other hand they don’t fight, they share food and also sit and lay close together – not really touching – without any issues. ”
Can you describe the bonding process a bit more?
They don’t all have to be crazy about each other, but one bunny just approaching the other as a trigger for a chase is a red flag. Bonded buns should be able to not only approach each other, but bonded bunnies will basically scramble all over each other without it leading to a chase or anything like that.
Even more importantly, your gut feeling that they aren’t quite bonded is the biggest hint that they aren’t. When they are, you will know!
The dynamics in groups are always different than the dynamics with just the two. I would actually recommend keeping all four together, but moving all of them to a new neutral space together, and seeing if you can do some marathoning there. Or maybe some stressing if that isn’t possible.
It does depend on whether you can keep monitoring them all in the current space you are in. If you can keep supervising, they might just need more time in the current space, but sometimes when you move too quickly to non-neutral they won’t resolve their issues and you end up with fighting.
