I have a newly built incubator room. Built into our porch. My entire first hatch in the room died, humidity was uncontrollable. I have learned a few things from this that may help others. First, the humidity was very high here outside and temps over 90. This really affected my incubators ability to regulate humidity. I got a humidikit and set it at 75%. I hatched turkeys, guineas and quail this time. Turkeys hatched a few days ago when weather was cooler, no problems. Today the guineas and quail are hatching and nothing but shrink wrapping in first few keets. I increased the humidity to 85. Chicks are hatching normally now with no help. So do not be afraid to really push that humidity at lockdown and during hatch. I will now have my humidity set high when we have hot, humid weather. And watch the first chick to pip and hatch. If it is shrink wrapped push that humidity even higher, even if you think it is good. I am doing Orpington, sizzle silkies, and maran eggs after these are done hatching and will hopefully have a problem free hatch after what I have learned. Hoping this may help someone else down the road.
