Yeah, well I figured out what was going on. I had noticed something while looking at the mom of the first litter. She had something none of the other females had around here her bottom. So that got me thinking. I looked online and found out how to tell the difference between males and females. Went over, looked at the "dad", who was clearly missing something, and while looking I kept feeling nipples. I looked at the "mom" and she had two big things the other rabbits didn't. So the reason all the babies died was because they had No milk. I am surprised the true dad didn't eat them. I switched the two, and now each is in the spot where they should be. I just feel so bad. it is because of us the babies died. We just grabbed the two white ones, and, don't laugh, we thought the testicles was stretched skin from being pregnant. How are we suppose to know? We haven't ever dealt with rabbits before.
