Last month we adopted two rabbits from a shelter. When we got them they were already bonded and love to groom each other and cuddle together. We are loving our two little girls so much that we have been considering adopting a third rabbit. 

I know rabbits are very social but is it wise to introduce a third into a bonded pair?

We would love to provide a home for another neglected rabbit but I don't want to disrupt the wonderful bond that our current rabbits share.

I have read about rabbit speed dating and I know that we need to let them choose their new friend but everything I read was about introducing two single rabbits, not adding a third to a pair. 

Thanks!

How long have they been a pair? If it's a newer bond, I'd wait awhile yet. It is possible that a new bun will cause them to "break-up", and then you'd end up with 3 separate rabbits. I always say why rock the boat if they are happy...

It's great that you're interesting in welcoming another bunny into your home, but I too would recommend that you wait a little bit. Trios definitely are possible, but they are in general a lot trickier and you could very possibly end up with a pair and a single or three single bunnies.

I have to agree. I think you will find it fulfilling to spend a lot of time getting to know these two. Living with bunnies is very life changing in a good way, and you haven't begun in just a month to get to see how they will interact with you as well as each other. You have years together, and a very good bond is not easy to come by. I would take it slowly, care for them, spend some together time with both and also some alone time with each one separately and learn more about their individual personalities. Eventually, when they need some health care, it will also be easier and less expensive to cope with two than with more. Your habitat, feeding, daily schedules are all going to be more controllable with a good bonded pair than with the additional complications a third bun would bring.
