My little banny hen started sitting on 12 eggs on the 9th of this month.....They are supposed to hatch the 30th.....I candled them ant there is like a large black dot surrounded by a clearish stuff and what appears to be veins......Are they still good????? One of them broke and there was a little baby inside. It was about the size of a dime. Is that normal for about ten days of incubation?????I'm all new to this and my hen is a first time sitter and I think she knows what she's doing....Please give me your thoughts!!!!!!!
