I am very sorry to hear about the sudden death of your rabbits. Unfortunately, without a true post-mortem examination, making a positive determination of cause of death will be impossible. In general, some causes of sudden death in seemingly health rabbits would include cardiac abnormalities, poisoning, and ingestion of a foreign objection resulting in choking or bleeding. Since you recently moved them to another pen and multiple bunnies died, my suspicion is that a toxin could be involved. I would inspect the area thoroughly for any unusual plants or objects. I would also be curious to know if the pen could have been accessed by other wildlife, potentially even something venomous or poisonous. Once again I am very sorry. I hope this helps a little bit.
