I have one chick in the bator that was having a really hard time coming out...one of the last of 12. I finally decided after a whole day to help him along. I took some of the shell off and let him have a go at it and he still wasn't able to do much. So I removed the rest of the shell and now I see that his yolk sack is not completely absorbed. Is there any hope? Should I do anything? He's still in the bator and I'm just not sure what to do. Any help would be appreciated. Thanks.
