Hi. We had a similar experience with our rabbits in December. We bought a pair of 'demi sauvage' rabbits. They proceeded to escape and be re-caught several times...very unsettling. Finally, the doe was caught and 2 days later had a litter of 9 kits, 6 of whom survived. She reared these very nicely, bu to our surprise, once the first lot had been weaned, she delivered 9 more! She had not been near the buck in all this time, so we were surprised. We hoiked the first litter out of her hutch and let her get on with it. The second litter are now nearly 6 weeks old and doing well. We have put the all outside in a run, and put the into seperate hutches at night for safety. I phoned my dad to ask him about it ( he is an old farmer!) and he said that females can sometimes carry two pregnancies concurrently, but its unusual. I think the best thing to do is to leave them well alone and let her get on with it. The next hurdle will be killing and eating the first litter. (yikes!)
