today is day 18 on my ameraucana eggs. I bought them on ebay so keep your!! I hope they do better than my last hatch. Out of 18 delaware eggs only 4 hatched 7 were fully formed in shell but dead 2 were quitters and the rest were clear. then on my white rocks I set 8 eggs 2 hatched and the rest were dead in the shell fully formed. I have kept everything perfect this time I know for sure. But these are shipped eggs so I don't know.I also have red star eggs in my new Brinsea octagon 20 advance. it has auto temp and humidity I am going to candle them tomorrow to check and see how they are doing it will be day 8.
