help with eggs!

[Nichole Murphy]

I have started incubating and I've followed this eggs process throughout the 21 days and I am confused as to if it has died or not. I had it on lockdown, temp normal and humidity to the correct one. This is my first time candling since day 19 So I am slightly confused

If that egg is 19 days old, it's dead.

At 19 days, the entire egg should be completely black. That means the chick is fully developed. Sorry!
