This chick was shrink wrapped, or at least beginning to. We have already had one that was, so I added water and then tried to get this guy moist. Well he hatched mostly on his own. (He had turned in the egg to finish zipping and was stuck, I had to remove some egg shell as to not drown the little one.) He came out of the shell in one mighty push. I thought good, he will be fine. Then he fell over. He has this green thing hanging from his abdomen. I am not sure what it is and what I should do about it. I don't think it is the yolk. He did have dome yellow goop stuck to his face, but I left him alone and it is gone. Anyone know what I should do?
