I have two broody silkie hens sitting on eggs. They are not all due to hatch on the same day. I did not pick up eggs for a few days and these two rolled them into their nest. I have had one hatch, one that got cracked near hatching, and 10 more to go. I have seen movement in 7 of them. Not sure about one and pretty sure 2 are no good. This is my first time hatching chicks and my hens first time also .What do you think about these two eggs? One had two dark spots that are free floating .I can see an air sac, but don't think any veins. The next one had an air sac and seemed close to having hatching two days ago and now the air sac is gone and I can see light spaces through the egg in places. I don't think any movement.
