I've got my eggs, 5 frizzle, 5 Naked necks 5 silkie. I've had the bator at 99.3-99.7 for three days, humidity fluctuates a lot, holding betwen 45-60% It was 33% when I got home today so I added water. The eggs are warmed to room temperature. I'm all set. Do I put the big round end up? I've read humidity should be between 40-50% first 18 days is that true? Is a spike to 60-70% ok? Ready, SET, GO!!!
