This is our first time hatching chicken eggs. We have two out and they are pecking at the other eggs and each other. One of the eggs they are pecking at now has an open hole and blood. The other egg has a chipped shell where they are pecking but the air sac isn't broken yet. It looks like its shrinking though and the movement inside is slowing down (breathing specifically). What should I do?! Humidity is at 70%, heat 99.6. This is day 20 and the 2 chicks were born at 3:45pm and 7:45pm yesterday (10/17).
