Hi, this is my first time incubating eggs and I only just came across your article on relative humidity and how to check air cells.... So, my chicken eggs are at day 13.... all 14 eggs show active signs of life..... But air cells appear to be closer to the day 7 illustration than day 14....... I have a Borotto sirio humidity controller (might have been a waste of money cause I can't seem to set it below 40%H) It has been set at 45% since day one and periodically RH goes higher (46% to 50%) Am I to assume since the air cells are too small that the humidity is too high and is it too late to help this hatch? I could pull the cords on that humidity controller ..... but my hygrometer won't fit in the incubator properly so I'll have to guess at humidity. My incubator is a borotto 16...If I remove the humidity controller... Mfg. recommends filling the front tub for the first 18 days (which should allow for 45% humidity according to them) and then filling the back tub in addition to the front tub for lockdown (to achieve 65%) IF I'm able to decrease humidity by pulling out all water source... how far down should I go? ANY assistance would be GREATLY appreciated!
