dead rabbits

Question
my rabbit has just given birth too twelve babies on the wednesday and by friday within a couple ov off hours we found 2 dead out ov the nest but there is still another baby in there from the recent litter and shes 10 weeks old and then on the saturday there was a third baby found abandoned but luckily it was still alive could this be the 10 week baby gettin jelous or is there too many babies for the mother too deal with.

Answer
Baby rabbits have very delicate digestive systems, and they also chill quite easily. There are many things that can kill babies. Other babies will not attack or drive out their siblings like some animals will, but at 10 weeks the babies should be weaned from their mother, anyway. It is quite possible the mother drove them out because babies should be weaned by 8 weeks old. Longer than that, and you risk both an attack from the mother and the possibility of one of the males developing early and getting the mother pregnant again.
