My lil silkie pullet hatched out three chicks yesterday. I just checked on them and all three are dead in the nest. I am so upset over it. I just assumed that she would be a good mama. She is still just sitting on them and the other three eggs. And she is still letting the barred rocks lay in the nest on top of her chicks. I pulled a fresh egg out of there today. So I am going to get rid of the dead chicks and let her sit on the other three eggs for a few days to see if they will hatch. How long will she keep sitting?
