Day before I check up on the fuzzies, their eyes haven't opened up yet. Counted 5 females 8 males. I could see the little indent spots on the females and the males didn't have them. I assume it was the lard I gave the moms is why there are more males based on the govt studies. Today I check up on them and I see half of a fuzzy, I guess one of the mom didn't like that I check on them too much and ate one, hopefully, it was a male... Any suggestion of clear plastics which works best? I like keeping numbers of litters ever possible.
