I look for quitters. I don't want to risk an explosion. I look for development that's way behind the other eggs and no movement. As long as the development is right around the others OR I see movement (or anything I can justify to myself means I should give the chick inside a chance, then I leave it). It actually takes a lot to get kicked out of my incubator.
I wm always afraid that I will remove one that was good. If I am notvsure it stays in.
I'll wait to candle on Friday; that will be day 13 for me.
I
want to candle on Monday too, but I'll sit on my hands...
I try to remember to mark the air cell at lockdown.
Are we all agreed to candle on Friday for the eggs due on/about the 8th/9th?
