I decided to set early, but will still want to see who else is hatching. I do not have any frizzle gray eggs currently, I will start a second incubator, and if I get gray frizzles eggs in time heat them in second incubator til the temp comes up then combine. these eggs will be slightly delayed since they waited 2-3 days before setting. I have had luck with this incubator before.
This is my incubator I am going to use, below are the eggs again, I got from a farm near by, the blue one, I was not going to set because of a loose air cell but changed my mind.
below they are in incubator, plus one from my flock, prolly a clear, see the blue is in a card board holder to keep up right, cardboard has holes punched through out. Also there are water bottles surrounding the out side edges inside incubator to hold heat.
Below is my extra incubator, heating up incase I want to warm up more eggs to add later...
