My Silkie Big Mama has been sat on 7 eggs. One chick hatched successfully on the 14th but nothing else has happened. She is still sitting on the eggs and taking care of the one chick. Today, I decided to candle the eggs which I did using black construction paper rolled into a cone shape leaving an inch diameter to sit the egg on. I then put the cone on top of my flash light. I've never done this before so it was pretty interesting. One of the eggs definitely looks empty, however the other five all have a black mass covering a third of the egg. Are these chicks likely to hatch? The eggs are from different Silkie hens that kept popping them under the broody.
