We are up to 5 chicks,first four did fine. However the last one was not fun. The chick pipped out the side below her air sac yesterday, I waited until this evening and she had made no progress and was simply breathing out her "air hole" I decided to help her as she seemed to be tiring. I was successful, without blood loss, but she is small and was very weak. She lay on her belly for 30 minutes without opening her eyes, but is now walking around and complianing. Her umbilical cord is still attached to the egg and a little of what I think is from the yolk sac (membrane with blood vessels). Hoping that come off as she drys. I am not sure why she pipped early as the temperature and humidity were well controlled. Hoping she is ok in the am. I put in a high walled box to decrease her movement and protect her bottom. I am leaving her in the incubator for the night. Any other words of advice on her care? I am concerned this hatch is not going to go as well as the last, the twin egg has not pipped and I am not sure about viability at this point.
