My chick hatched about 3:30 this afternoon, and it's backside/belly was really big. Since it came from a big egg I assumed that it hadn't completely absorbed it's yolk sac, but everything seemed enclosed so I didn't worry much. Now though there is some blood coming from the area and a red string like thing. What's wrong with her? Can I help? She is still a little wet, and in the incubator. Please let me know what to do!
