I have another batch of eggs ready to go. I separated the birds into breed-specific breeding pens when this batch went into the bator and started gathering them during lockdown, so they are nice and fresh. Some will be black copper Marans, so same hens but different rooster this time on the brown eggs. I'm going to also set some more Ameraucana eggs from the same rooster/hens combo even though I don't need any more Ameraucana this year just to see if the weird 0% hatch rate happens again or it was a fluke.
You do realize that it can take weeks for a hen to completely clear from a rooster after being removed from him? So if these eggs are not around 3 weeks +/- after taking her from a certain rooster they could still be some of his.
I did mention I feel you have to much air vents in the incubator unless the Styrofoam is blocking off some of it. As far as the fan---I would have it blowing on the bulb, but never experimented with it the other way so it might not matter.
As far as the blue eggs dying because of the incubator----I do not see it-----you said the blue eggs were in different locations through out the turner-----if they all were in the same spot in the turner then might need to try to figure out a problem. I have hatched MANY blue and other colored eggs and never had a problem with them.
