I have now incubated 2 sets of chicks with my Farm Innovator 4200. My overall stats are really good, yet I am having an issue with sticky chicks and have lost a few because of it. I am so confused about the thermometer and hygrometer, on the top of this unit. I don't know how to properly figure out the actual humidity and I end up using the hygrometer, as the humidity number. How do you determine the appropriate humidity? I have purchased two other thermometer/humidity sets, but, of course, nothing shows the same percentage or temperature. I hope this makes sense. My husband wants me to incubate duck eggs, but until I get this figured out, I am a worried about ruining their ability to hatch. I love my Farm Innovator unit, I am just confused and have read so much, that I am totally confused. THANK YOU SO MUCH FOR YOUR HELP.
