Well, maybe I am finally getting it. Today I had a 100% hatch in my Brrinsea Octagon Eco! This is about my7th hatch and each time the best I have done is about 70%. Where the eggs came from didn't seem to matter. These were14 Ameraucana eggs that came from my own Am. chickens and Am. Roo and 4 of them came out of the refrigerator (!!!)Just had to tell someone who would understand how truly wonderful this is!!
