So I had one egg hatch 2 days overdue. I had to help because after 48 hours it was struggling to zip. Chick is out and healthy. I floated tested the other 3. Two floated sideways and one floated straight up and down. The guide I was following said if it floated up and down that it was dead. I cracked open the wheel and it was moving inside. A little blood came so I put it back in the incubator along with the other two. What are the chances that one will hatch? How about the other two? Humidity is in the 70s
