I have a question about humidity. If the humidity is too low during the first 18 days but accurate the last three days, what happens?
 
Chicks can either get stuck in the membrane as there wasn't enough moisture, or it can cause deformaties in the chick. See if they hatch and just watch out for lack of progress, they could hatch fine or maybe you will need to help out at the very last minute. Helping out a chick to hatch can be dangerous for the chick as the chick needs the struggle to flex its muscles to absorb the yolk into its abdomen which feeds it for the first day or so. Also, the chick needs the struggle of hatching to strengthen its legs, otherwise they could be 'splayed' and / or with curled toes.

Hope that helps.x
 
yes, a hydrometer tells you the humidity. I got mine from ebay. I cant recall perfect humidity off by heart, but its something like 60% for first 18 days and then the last three days its up to something like 80%.. but if you search humidity on here someone will have written something about it. :)
 
The older reported 60% then 80% last three days of incubation has really been dissproven as the standard. Some adjust humidity based on egg weight loss or by monitoring the air sac growth via candling. These methods take more involvement and experience hatching. The majority of us incubate dryer than the old methods to great success. 35-40% humidity first 18 days then 55-60% for hatching is the new standard. Keep in mind that proper temperature is far more important, turning of eggs when stored and during incubation second and lastly humidity is a factor for hatching success.
 
I keep my eggs at 45-50% for the first 18 days and up it to 65% for the last three days. When the chicks start to hatch, you're humidity is going to soar to upwards of 80-90%. My first hatch, this freaked me out and I panicked. Don't do this.
 
sallysunshine has an egg hatching 101 thread. Look her up, check "Pennsylvania unite" or PM her.
Her recommendation is what I have found the norm. 48-50% the first 18, and 55-60% the last 3 days.
She will even tell you how and when to help.
