so I have chickens in the incubator (10 barbanter, 12 silkies. One day apart) about 7 hatched (7/10 barbanters) 48 hours ago. The other didn't even pip. So I took the live chicks out. Left the other eggs in an extra day, still no progress. I took them out, candled and saw no movement. I went to open them up to see and 5 were dead and 10 were still alive after I removed the air cell. I freed their beaks (3 I didn't free their beak as they are not in position to yet), wrapped air cell area with wet napkin and placed back in incubator and raised temp. 24 hours later all are still alive and chirping but their blood vessels are still visible so I can't assist hatching. Any advice? They are show silkie chicks.
