So few months ago I got another rabbit who I named Mako(around 2 years old). I letted him get used to the new place before trying to bond with my other rabbit named Carmen (1 year old. both are neutered boys). Then came their first session of trying to bond them but it didn’t go well so I tried to pre-bond them first. About a month or two later I started with stressbonding. It went somewhat well but not the greatest. I did the stress bonding everyday. First once then over to twice a day then everyhour. Then one day Carmen got out of his enclosure (which was my bad. I admit it.) while other one was roaming around. He got attacked by Mako. There were no serious injuries but there was small one that healed on it’s own. Then I stopped with whole bonding and tried to “soften” the new bun. Get him more used to me. At that time he was more shy. Now hes still a little shy but not that shy like when I got him. In the morning when it’s their food time then he comes up to me wanting his food. Usually Mako (the newest one) is outside the enclosure at night time while Carmen is at day time. But ofcourse if im away at school or somewhere for more than 5-10min then I make sure both of them are locked up.
Today when I got home and let Carmen out of his enclosure I saw that his left ear was bitten. Its not bleeding but almost a piece is kinda hanging. Kind of like when you cut paper but you only make a small cut right on the side but you don’t cut anything off that paper. If you touch it then you can see he doesn’t want you to touch it. Im pretty sure his ear wasn’t like that yesterday & I don’t remember his ear being like that this morning or I just simply missed it. It might’ve happened at night. Or when I was at school somehow.

Both of them are in my room. Their enclosures are few cm’s away. When Carmen is hopping around then he goes to into every room but when Mako is running around then hes only in my room. Hes kinda shy of going into other rooms. I used to put a blanket around one of the enclosures because of Mako trying to attack Carmen. But then for some reason I stopped doing it. For that Carmen can’t lay down or go too close to the side of enclosure because of Mako. I should probably start putting a thin blanket or cloth around the enclosure once again when Mako is out.

I got Mako from a lady who got him from a shelter. I think she is fostering pets from the shelter. The lady had Mako and guinea pigs together. They did well together.

So what im asking is what am I supposed to do now? I don’t wanna get rid of Mako or Carmen just because the bonding hasn’t been successful. Any help is appreciated.
