I am setting up my incubator to hatch eggs...I have always used an automatic turner and this time I do not have one...can anyone tell me about how to turn the eggs correctly...everything that I have read says two completely different things...please let me know...I am only putting in about 18 or 20 eggs...I do not know how this will turn out it is only my second time using an incubator...I am scared because I do want to have a good hatch...I know lockdown on day 18 so I am going to set them in on the 10th and have December 1st babies...I hope someone can help me out...I was not worried last time but I am this time...also humidity is another issue I have never used this incubator before so should I fill all the water rings with lukewarm water? Or just fill two of them?
