Using Miss Prissy's instructions, I (well my husband) built a cooler-bator. I'm testing it out now to see if we got it right. I'm very excited at the prospect of hatching larger amounts off eggs. I've been using a mini-bator, that everyone on here says doesn't work, but it does--you just have to watch it closely. So anyway, I like the mini-bator, but I need more room!!!!
