I could see a yolk in all of them, some were larger than others, but i saw no veining. today is day 7. i'm not going to scratch them because i'm not sure if they are alive or not. maybe i couldn't find it because i didn't know exactly what to look for. also, the light i used might not have been strong enough. the temp and humidity have been rather wierd. temp has been holding steady lately, but the humidity is all over the place. never too high, always too low, sometimes just right, but then it falls again. do the eggs still have a chance? i was excited to candle to see if they were growing, but i was also worried because i was afraid i would run into something like this.
