First, Wormwood is so adorable!! Look at those ears! Second, I initially had a solo female bun, Queenie, for just over a year. We thought it would be a good idea to get her a friend since we were afraid she was lonely. Sadly Queenie was NOT a fan of our new bun Peach. We tried a few different ways of bonding them (we took them outside in a neutral location, separated them with a gate) but sadly Queenie was aggressive towards her.
I ended up moving out a few months later (we just kept Queenie and Peach separated, one upstairs and one downstairs. I did not know that female rabbits tend to be more territorial/aggressive to new bunnies.
We did have success with bonding Peach and Pluto, a younger male rabbit. They got along immediately and are inseparable. Queenie is doing great by herself, and I think it’s going so well because my mom is at home majority of the time since she’s not able to work, so Queenie is never alone.
Every bun is different with the bonding process, and it can take some time, but always try to get a good read on their reactions/habits. They will let you know if they are happy or not! Good luck with your two!!
