Hi, it is day 21 of incubation and my 8 chicken eggs are still not showing any signs of hatching? They are not pipping, making any noise, or moving. I candled the eggs before lock down and everything seemed fine every baby chicken was moving inside their eggs, but now they are just not hatching. I know that if the tempature goes down they can take a little longer to hatch, but the temperature in my still air incubator has done a pretty good job of staying at the right temperature. Right know the temperature is at 99.5 degrees and the humity is at 71%, so I am not sure why they are not hatching? I am really worried, and what to know why they are not hatching, or if I did anything wrong during incubation? So please comment back with some answers.
