I just had 9 Silkie girls go broody, the problem is that I have 5 of the hens in a pile sitting on eggs. The first chicks started to hatch and a few died under the hens, a few are alive and thriving but I had to give them to my Showgirl to mother them, the 5 did not pay attention to them at all. Now I noticed that they have eggs that pipped and have about half the shell off under them but the chicks are not alive. Why might this be happening? Should I toss the rest of the eggs and try to break them? Should I candle the ones they are setting on to see how far they are developed?
