I ask this question because Im at the end of day 18 and ive heard nothing from my Silkie Bantam eggs. I dont have a real egg candler, but I held a torch up to them around day 9 and I could see what looked like lots of blood vessles and the eggs looked quite dark. When I "candled" them again on day 16 the eggs were completely dark except for the air cells at the end. So im guessing something has or had grown here but im just not sure if anything going to pop out on tuesday morning
