hi! I have a a air circulated incubator with pekin Duck eggs inside my humidity is about 70 I think it should be lower, but let me know what you guys thinks! I was wondering if you knew how to lower the humidity?
Reduce the surface area of the water. Smaller tray. More ventilation? Maybe you can also cover part of the water or float objects in it? I'm sure someone has a better answer has well. I believe adding salt will also slow evaporation rate.
Lower it to around 50 for incubation, jack it up to 80 or slightly higher during hatch. If you need to cover part of the water pan wih tin foil to reduce the surface area of the water.
I don't know how to reduce the surface area because I have designated slots in the bottom of my incubator and directions say to fill it with warm water
Are all the water slots connected, have you tried only filling 2 slots? That's what I did with mine and it chills around 40 (chickens, 6 water slots). Maybe fill one or two more if you're looking for something in the 50's range. Every incubator is different so you might have to do some calibration before you get it right. What brand is the incubator?
Its a lot of trial and error. What brand incubator are you using? Each brand uses a different system for providing humidity.
