My largest litter was quads, but only two survived because they were the "bullies" and they killed the other two who were the runts. I had a mom die in labor and then I went in to see what went wrong and she had 5 kits in her! But 1 was huge, 2 were normal, 1 was a runt, and the other was already mummifying/decaying. I felt really bad for that mommy (Annie). I felt helpless with just watching her die because there was nothing I could do.
