Thread: Where have all the bunnies gone

New born rabbits are immune to virus and disease until about 6 weeks old ( from memory) @6x47 is right you should see more young around than older rabbits. That being said we did a lot of blood sampling during and after the releases ( we had to head shoot rabbits and extract about 3-4 mil of blood from the still beating heart and this was sent away for testing for anti bodies to the virus, each sample into a separate vial and new syringe and needle each rabbit) We found that quite a large portion of older rabbits had the anti bodies so they were immune for life.
