Day 8- how do I get humidity past 45?

[rroven]

I have put 2 sponges in the bator, the wells are full and I have reduced the air flow being pulled out by the fan and I also blocked the top vent so only the bottom vents are pulling in air. The humidity was at 38 and now after doing the above it is still only at 45. This is a LG still air we installed a PC fan in. So, what else can I do? I lost 10 chicks in my last hatch due to the same problem. They were fully developed, healthy chicks that couldn't get through the membrane. I have 36 eggs in the bator and I would be happy with a fair to good hatch.

The average humidity in my bators are around 42% for the first 18 days. Why are you wanting higher humidity levels? You have to reduce the size of the air cell and its hard to do with high humidity levels.

45% is okay for a day 1 to 18...you want it anywhere between 40 to 50%....
