Today is day 7 in incubator,I have 2 questions, I have kept them upright do to fact that they where shipped eggs & unable to see in them (Marans). I can tell that the air cell is in the right spot, should i keep them upright or lay them down. The other question is what does anyone use to candle Marans eggs & blue eggs successfully, I have a LED flashlight. I am new to this and advice is welcomed.Thank you
