well... to first answer the runt question... after a few weeks you can't tell... runts grow quickly to normal size...
However.. to answer the second question... well normally an animal that was killed is no longer breathing ... another proven method look to see if your rabbit has a head..... it not it may be dead..... (here's your sign)
It depends on how many there are in the litter. Like if there are three she will probably keep it, but if there are six she might abandon it. Remember every mother is different. My Rabbit killed hers, she had 3 in her litter, and she dragged him out side of the nest! Still if your mother rabbit is feeding the rabbit, then it is not a runt!
The rabbit may have a runt in the second batch, but just as well may not. It depends on many factors including the buck, and how many kits are in the litter. One cannot say that she would or would not have a runt for sure.
If its not moving at all and if it smells funky, it was probably the runt and died.... sorry...

Runt
Runt - (noun.) English: Runt Spanish: Respido French: Treveta German: Goolinvet* Dutch: Arsterweig *This is not even a German word, I do not know where it came from. The best word in German would be "Kümmerling" or "weakling".
If the runt of the litter is in anyway sick or injured it is possible that the adult females will abandon it, leaving it to die, yes. Chances are that if the runt has been torn apart as (grusome as it may be) it was already dead or it was accidently killed when to females were fighting over who would care for it.
