My silkie has been sitting on her nest now for about 22 days. I when I candled the egg all the space inside is dark except the air cell. I'm worried that the chick has died. There is no peeping or noises like pecking coming from inside the shell. I'm just really starting to get nervous. Last time one of my chickens broody only 6 out of 20 hatched Is there a way to tell if the chick is dead other than being patient? Unless this chick is going to be fashionably late like its dad who hatched a week late.
