I have 4 eggs still in the incubator. All the other chicks hatched yesterday. Except I think three died during lockdown. No internal pip, no movement during candle..... I have a Silkie who has been trying to pip for about 14 hours now. She's trying, I can hear her peeping and pecking! Just no pip! I'm worried the shell may be too thick to pip.... Should I make an artificial pip to help her? I wouldn't ever unzip. Just maybe help her get the pip. She just keeps peeping louder as time passes. The egg is rockin and rolling around. She just can't seem to get through the shell.
