The thread posted above was mine. Put them on pause when you can't sit right in front of them and hunt mushrooms. When you are babysitting, put them on 2X so they grow up faster. You can make it if you are obsessed about it. You may lose some, I ended up with only 6 out of 18, but hang in there. Be sure you keep at least one male and one female alive too even if you have to sacrifice some others to ensure you can rebuild.

Good luck!
