OK i candled my eggs to day, day 7 for me i used a 1 million candle power halogen spot light. from what i can tell i only have 5 good eggs out of 18 all the americana eggs have a big yellow blob in them but i don't see the little black spot or any movement. i got the americana eggs for free any way. i seen her take them right out off the nesting box right before i left maybe they were old. now the maran eggs in 5 of them i seen a black spot moving and an air sell 3 of them had a blood ring and 2 I'm not sure about. what makes them get a blood ring? and what makes them just have a yellow blob with know black spot? my temp did get down to 98 a few times the first 3 days.
