Yes Did that before lockdown. The one egg I did candle looked like there was a chick inside as half was dark the other half though I couldn;t make out veins at that stage but my candling effort was not that great! It is hard to hold an egg a torch and pull a coat over your head inside a dark small closet! Lol!
Anyhow last time last month it was the same. Half the egg dark and "moving!" but when eggtopsied it was just slow cooked scrambled egg
That is a real bummer :c The post is fantastic at destroying eggs!
