I must have the worst moms in the world. About 1 of every 4 litters gets killed/eaten/smothered/neglected by momma. any reason why? I fed two of the bad moms already, I cant have that goin on. The others are absolutely wonderful, but some are just bad.

Any words of wisdom? I imagine the consensus will be, "keep the good ones, feed the bad ones" but I just wanna double check...
