I just noticed the date of your first post. Is the dead litter the same litter that you posted about 10 weeks ago? I'm not at all clear from your posts what happened to your rabbits. You don't make it clear if she killed them or something else caused it. You say she killed them and you also say she abandoned them. Were there any injuries? Did they die overnight or over a period of days? Were there any of the usual signs of illnesses? A little more information might help determine what may have happened or to point you in the right direction in case there is something you might do differently in the future.
Does do not abandon litters at 10 weeks of age. They have long been weaned from the mom and she was done with them. If you've left a litter of bunnies in a cage with the mom for 10 weeks, she might attack and kill them. How long were you planning to keep them with the doe?
Bunnies start to wean themselves at around 3 to 4 weeks. I usually moved them to their own grow-out cage at 5 weeks or so. If they were in the cage after that, I had to watch them closely as I found leaving them longer than 6 weeks was asking for trouble.
I would get a good book on basic rabbit care and breeding and understand that fully before re-breeding the doe.
