So I ordered eggs offline. i followed all shipping egg tips before I set the eggs in the incubator. i lost 80% of them by day 14....just no development and a couple blood rings. This is my first time incubating. I have kept my humidity at 40-50 during the first 18 days and 75-80 on lockdown. My temperature had varied from 99.3 to 100.5. I bumped it at one point and to had to recalibrate but there were no extreme temps for over a minute or two. I saw movement in the eggs on day 18. I am on day 21. There is no movement. No pip. No nothing. What should I do? Candle? How long do i wait?
