I think it’s possible, but it would take time and consistency on the owner’s part. I only have Wick, and he’s been a single bun with no bunny interaction since he was 8 weeks old.
A while ago, I made a post about how Wick didn’t seem to know he could use his front paws to dig through hay and stuff. I got him small toys to stuff food in for food engagement, and from that, he eventually learned that he had front paws for digging. He is 1.5 years old now and starting about 2 months ago I’d say, he is now digging through his hay like a “normal” rabbit.
I do practice reciprocating grooming with him, to the extent that I mimic what I’ve seen bonded rabbits do in social media clips. I give him his turn to groom me, then I groom him back. When I stop grooming him, he grooms me, and then I reciprocate, and vice versa. I’d like to think that’s teaching some communication cues, though I’m unsure. If I lay next to him, Wick does settle down to a lounge and the grooming begins, so one way or another, he gets it.
And yes, squealing at biting.
