This was the first time that I've tried to hatch some chicken eggs. For my hatch I'm using a GQF Model 1588 Genesis Hovabator Egg Incubator with a egg turner. I started out with 40 eggs that i purchased near by and some from my own hens. When i went into lockdown there were 30 good fertile eggs. With the particular model its already pre-set to 99.5 and the thermometer read the same thing throughout. I don't know what went wrong. The 3 that did hatched, all hatched a day before they were do, if that helps. Any help would be great. Below is a pic of the actual incubator i was using and some of the eggs that i was using. I need all the advice i can get as i plan to try again.
