I have 1 chick out who is still attached to his cord and is dragging around a huge piece of shell. At his body where the umbelical cord goes in it looks like its pulling it open every time it struggles. Its very wet almost bloody looking. I have another chick pipped right now. Should I open enough to slip siccors in and free chick So it doesnt pull it open more and risk damage or death? Or do I leave it alone......
