wasn't a total flop, I got one baby out of it, but the other 7 didn't. I finally gave up today at day 25. I checked the insides to see what, if anything, went wrong. I've since determined that the temperature was too high. I had the thermometer staying at roughly the same 99.5. Turns out it was closer to 101.5-101.9. Fertility was 100% though. I tweaked the other batch so hopefully it does better.
