I feel your pain. REALLY! I have had 2 bad silkie hatches (one in incubator and one under broodies) and was crushed when the only two that hatched out of 12 were found dead the next day. No visible reason, perhaps the broodies smothered them, I just don't know. I swore I wouldn't buy shipped eggs again and gave up. Then a kind breeder sent me replacement eggs for the last batch and I am trying one more time. They are under a broody hen now and today is day 21. One pipped last night and hatched almost 18 hours later. The others (4) that candled "full" have not hatched yet. So, I'm hitting the wine tonight! HA! I'm hoping for 5 babies out of the 12, but who knows. Last time when I lost them all I cried for 2 days. The let down after the joyful anticipation was just awful. I don't have any good advice or words of wisdom. I can only say, I understand and sympathize. If this third hatch fails, I will be forced to give up on hatching my own and just buy chicks in the future.
