I am going to try to add as much info as possible so I apologize in advance if this is a long post.
So I have 3 lovely bunnies that I am trying to bond. Two males(Scout and Sawyer) and a female(Sammy). All of them are fixed, Sawyer was the last to get fixed and that was in the first week of February. The female, Sammy, and Scout are a bonded pair that I have had for a year. Sawyer came to me unexpectedly in late January and was not fixed so I kept him separate until he was and the healing process and last bit of hormones were out before I tried to introduce everyone.
So here is what has happened. The female and new guy got along fine. Sawyer mounted her once and after that they get along like cake and ice cream. The boys are a different story. From minute one scout has tried to attack Sawyer. Not just fur pulling, but actual bunny hurricanes and one incident ended with a trip to the vet for the new guy. This even happened the first introduction time in neutral space that was set up to give them space to run away and hide but not too much space. Any scuffle was broken up immediately since it was obvious this wasn’t mild fur pulling or mounting. To clarify, Scouts biting was so aggressive that the first intro ended with me needing stitches because he bit me because I was holding Sawyer. Scout has never been aggressive before.
So after neutral space intros didn’t work I attempted stress bonding by taking them on car rides, a vet trip, etc. Even under those conditions scout tried to attack. Poor Sawyer just wants to love him and can’t seem to understand why he’s being attacked. He has only bit scout once and that was in self defense. I wish I had videos to show what happens.
So for the last 6 weeks I have been keeping them apart and swapping them spaces so they get used to each other’s smells. And I have recently began setting up an X-pen so they can see each other but not attack as easily. Scout tried to bite through The bars still. The problem is I don’t have the space to set them up next yo each other, so they are confined to separate rooms unless the pen is set up. And even then I have to be vigilant because Sawyer can clear the 3.5 feet to get in. I’ve never seen a bunny jump so high! I did get them to share space once. For about 20 minutes, they even snuggled, but then scout changed his mind and ran away and tried to fight Sawyer 10 minutes later.
I keep Sammy and Scout together since they are fully bonded, and Sawyer gets the cats as friends. But this set up is stressing everyone out since no one gets free range of the house anymore.
I am just not sure what to do anymore. I try to take baby steps and nothing seems to help. I can clarify if I need to and please ask questions if you need more information. I just need help here. Does this seem like a hopeless endeavor and I should be looking to find a way to better keep them permanently separated in the house? Or should I just keep trying? I feel like the only issue is scout, and I can’t figure out why he hates Sawyer so bad. When I tried stress bonding and sticking them in a dry tub Sawyer tried to groom scout. Scouts response was to try to bite his face off. Please please please help!!
