With my first hatch, this week I had set 8 araucana eggs - 1 never developed- all 7 fertile eggs hatched which is simply amazing. I set 19 araucana x polish and 15 hatched. Again that is good.
The biggest thing for me was being able to set the eggs and walk away. I checked them every couple of days, maybe add water maybe not. I did raise humidity to 50% during hatch and it went up to 65% when a chick would hatch.
You have to remember, I built my own cabinet incubator and my hatch rate was 50% to 70% depending on the weather and the incubators mood. I had massive hot and cold spots I was always fighting. But I built it and loved it. It only cost me $60.00 except for the egg turners.
I would recommend getting the egg turners for the LGs. That way you arn't messing with temp and humidity 3 times a day.
