I have six chicks in the incubator and all hatched fine except this last one. It struggled for over 10 hours and when it finally broke free it had bloody bump on its stomach and blood in the shell. Now all the others are pecking at that bloody spot and he is very weak. There are two others pipped. Should I open the incubator and get the others out (one is 24 hours old and he is the one doing most of the pecking). I can't bear to watch this.......help
