Will two female rabbits kill each others as i have in together and both are pregnant one is already delivering?

It is possible for two female rabbits to kill each other, even if they are both pregnant. Rabbits are territorial animals and can become aggressive towards other rabbits, especially if they feel threatened or their young are in danger. If you have two female rabbits together, it is important to provide them with enough space and resources so that they can avoid each other if necessary. You should also watch them closely for any signs of aggression, and separate them if necessary. If you are not experienced with rabbits, it may be best to keep them separate until after they have given birth and their babies are weaned.
