I was candeling my 26 eggs and noticed 4 of them were "runny" inside. I cracked them open and sure enough the yolk spilled out in a watery mess and they were not fertile (luckily I did. This in a plastic bag) but one of them actually had a live baby inside I could see its little heart beating away and I feel so guilty... Could the chick have survived with a broken yolk or would it have died before it was supposed to hatch? (It was put in on 6-6). I didn't break the yolk it was already broken when I candled it, which is why I cracked it open. What could cause this? Is it something I could have prevented?
