I'm putting the cart before the horse here but my hens should start laying any day now and I've got 40 of them so I'm gonna have a surplus of eggs and quite a few people have asked me to hatch them some chick's when I get extras. I've pretty much decided on the hovabator 1588 genesis I can get it for under $200 with the auto turner. The only other I looked at was the eBay Chinese ones. When I was looking at the hovabator it suggested I order a humidity pump with it. How mandatory is one? I've read quite a bit of threads on here and only seen a few people using one. Most just add water to the tray in the incubator as humidity is needed. I have a humidity meter in my house and living on the Gulf Coast my humidity indoors rarely goes under 45% normally hovers around 50%. It seems like there's a huge range for ideal humidity I read between 25 and 75% in the incubator.
