injured baby rabbits

Question
One of my adult female rabbits gave birth to her third litter a couple of days ago.She was in with a female from her first litter and a male that people at the cat and dog home thought was a female because he was still quite young.I moved the male out into another cage when i realized he was a boy and kept the two females together.When the female gave birth to 4 babies i still kept the females together because the female from the first litter was great with the second litter but i noticed the babies had injuries like cuts and bite marks on them and one of them, the smallest one had half its ear hanging off and is missing its foot on its hind leg.I moved the female into another cage incase it was her but i found one of the babies outside the nest and it was dead and it was the healthiest and biggest out of the litter.They are still young and if its the mother they cant defend themselves because their eyes are still closed and they are helpless.I now have ten rabbits including the litter of three but none of the litter look healthy and i cant handle them because im scared the mother will kill them.
Its really hard to look after the rabbits because im only thirteen and i have school and clubs and because all of them are now in seperate cages as i have 5 males and two females.Two males are from the same litter and used to get along well but now they are constantly fighting and one is injured but not seriously.I dont have enough money to get them all neutered and spayed but i dont want to get rid of any of them but when the babies are old enough they will be rehomed.I really dont know what to do and i need help.Please help me!

Dear Rebecca,

A good first step was separating the rabbits, but the babies need to be fed, so please read this for instructions:

If the mother is not caring for them, you'll need to take over.  But more importantly, please read these two articles:

and

You can find a good rabbit vet here:

I hope they will be okay.
