They will continue to act dominant/aggressive unless they are both spayed. You need to separate them, preferably where they can still smell and see each other until after they are spayed and given time to completely recover (about a month). Even though they are mother/daughter, they will still have aggression/territorial issues that could result in somebun getting hurt.

Yep, this will continue until theyre both spayed. It may even get worse as the babys hormones start to come in as she gets older. Rabbits dont understand family relationships. If they see another bun, it is just another bun to them, not mom/dad/brother/sister. And when they see another bun, they establish dominance by mounting, fighting, chasing, ect until the other bun shows complete submission. If the other rabbit does not, rabbits will often fight to the death. This is why in order to house two rabbits together, they need to both be spayed/neutered.

I agree with the others – the buns need to be separated right away, close enough so they can continue to see and smell each other (for pre-bonding) but under no circumstances allowed physical contact with one another, and spayed (in the young one’s case as soon as she’s reached sexual maturity and is old enough for the operation to be performed safely), then kept apart for up to another month while the residual hormones dissipate. Only then can you begin actual bonding. That, by the way, will also allow the younger bun additional time to grow and put on weight without being hassled by the older one.

As Mikey says, rabbits don’t have a concept of family relationship. Their social structure as house pets/companions is defined by bonded friendships, and for those to happen, they need to be neutered or spayed. My own Panda and Fernando, who are coming home Sunday , are a good case in point. Panda is Fernando’s mother, along with the mother of three other kits. They were rescued in January/February by Friends of Rabbits (a rabbit rescue serving the metropolitan Washington, DC area) from a Maryland shelter not long after Panda had kindled her litter. While I don’t know exactly how it was all done, I’m very certain that the Friends of Rabbits people separated Fernando and the other kits from their mother once they’d been weaned and before their hormones could really kick in and mess things up, being allowed to stay in sight/scent range of one another but not permitted to physically contact one another, while each of them was spayed/neutered in turn, allowed to heal and get rid of their hormones, and then properly bonded one to another. It’s really paid off done the proper way – Panda was very close to all her kits once they were bonded, before the other three were adopted out, and she and Fernando are real cuddlebuns, they’re snuggled up with one another or grooming each other half the time and the other half they’re never more than a few hops away from one another. Establishing a parent-child bond between buns can definitely be done, it just has to be done right.

I have no idea.

This might be a silly/unhelpful question. But where is the bunny who got your female pregnant? And have you even identified the sex of the baby bun yet? Everything everyone has said about this not stopping until both rabbits are spayed/neutered is correct. I understand that some people might be unaware of having to spay for hormonal/health reasons and can sometimes only associate this with being done to prevent pregnancy. You might end up having more issues than just dominance if this baby bun is in fact a male. And if the male who got your bun pregnant with this baby is still in the vicinity this could add problems also. I know these aren’t things you mentioned or asked for advice on but I just thought I’d chip in with that aswell just in case.
