From what I read regarding a dry hatch I was thinking humidity should be 35% days 1-18 give or take, then 65% the last three days. Does this sound right? My incubator keeps the humidity right around 42% (as long as I add water) and as long as I put in a wick it will bump up to 65% for those last three days. But I wonder if I should try to get the humidity down to 35%. Also, I live in a very dry area... very dry! My ambient humidity is about 10%. Does this make a difference? My incubator holds the temp and humidity almost perfect, so as long as I know what I want that humidity to be, I will be in business. Most of my eggs are Marans so it's really difficult to check the air sac. I am open to hearing everyone's opinion. I don't often see people from really dry climates discussing incubation humidity. <---------------- I will be waiting by the computer to hear from all you experts. I just put in a lot of eggs Saturday and if I need to change my approach, I can do it now.
