I'm on day 19 now.
On day 15 I posted that I couldnt see any movement or veins..
At 3am day 18 I candled, still saw no movement or veins The egg is dark with an air sac. But no life like many youtube videos show. I have a bowl of water and a cloth inside for Lockdown, temperature is 37.3
I havent touched the incubator since the morning of day 18. I'm still concerned that my three remaining eggs are gone. :-(
