Thank you for that. Yes, I think perhaps a few more days at least in the bonding pen just to make sure they are still getting on. I am quite keen to get them into their permanent home as part of this is inside so I can keep an eye on them more easily and they will get more human interaction. However, I have a feeling that there will be a bit of friction when the original bunny realises it's his old home! The other thing is that the original bunny was perfectly litter trained and so tidy- judging by the state of the bonding pen the new bunny is not - it's a complete mess everytime a check and although they are using the litter tray sometimes, they are also using the rest of the run too!
