How do I regulate humidity in my incubator?

[Picklestix7866]

Hi guys! I have a still air incubator that I like to try to hatch a few Silkies in each year. I just don't know how to measure/regulate the humidity. I have an egg turner so I just squeeze in a cup of water and hope that it works. I don't have great hatch rates though (although somehow I did manage to hatch a duckling last year...lol). They start growing and then die before they get much bigger then my pinky fingernail.
Is there a humidity thermometer or something? It is a Little Giant incubator, and it looks like this :

Thanks!

Walmart, Home Depot etc sell digital thermometer/hydrometer combos pretty inexpensively. Pet stores also carry them for reptile cages etc.

Just remember.... it's surface area that counts! More surface area.. higher humidity... smaller surface area, less

Happy Hatching!
