Hello! I am hatching some silkie eggs, and today is the 21st day of incubation. The eggs are not moving, and I do not hear any peeping from inside. This is my first time hatching eggs, so I don't know if I should be worried or if I should just wait. I have been candling the eggs so I know all the eggs are developed (the eggs are in lockdown now), so I am going to keep the eggs in for a few more days without opening the incubator before I candle them again. The humidity and temperature have been stable and the humidity is at a good amount based on what I have read, but I am worried that I have seen no signs of hatching. Is this normal?
