Bunny Infromation

Question
I have 3 bunnies that have been for like 1 year old and is currently hostile to each other. I do not know why they are fighting each other and never even touch its food or water. I also need to know the lifespan of the bunnies and what environment it should be in. It became hostile ever since their mother died.

Answer
While I don't really understand this question due to a fragmented sentence, I am guessing that these bunnies are littermates and are now being aggressive toward one another.

One would assume that as rabbits go in and out of heat that they will tend to be more aggressive with one another.

I suggest you separate them into different cages. Other than that, I am not a bunny expert so that is all that I can offer. There are bunny experts in here if you care to re-post this to one of them.
