i have a bird sitting on 11 eggs. today is day 5-6 (not sure when to start counting). i had about 2 minutes to candle the eggs before she got pissy i took her off the nest. the light was not the best, but it was a light. there were a few eggs where all i saw was the air sac. assuming those are done for. i had several that i saw something floating around, again not the greatest light and she was getting pissy, so i did not have time to look for the eye, but as i turned the egg something floated around...embryo? i left all the eggs in there, hoping to get a better light for next time and get some answers. next time should i toss the ones with just the air sac?
