Hello,this is my first time for hatching duck eggs.I have 1 that has a nice size hole in the wrong end of the egg.Its got the egg really rocking,and theres alot of peeping,and i can see the bill.Is there anything i need to do to help it or can it get out of that end?Ive never had a chick do it,so i have no experience with it.Also theres no zipping just that hole since Thursday night.Any advice is appreciated...
