If no egg sack then it must be ready to hatch. leave it under mom unless you have a bator to put them in. But I have to say if mom opened and they are no ready veins etc they may not make it. Why didn't ya'll candle, much easier way for finding out whats going on with out risking losing any lives. It is all the way out of the shell?My mom got really nervous about the eggs and she decided to break them one was rotten and two others had goslings in them it is on its 28th day but it does not look ready. There is no food sack or what ever you call it so I am wondering what to do if I should just leave it or do something with it.
