I have a brinsea cabinet incubator and a brinsea octagon 20 EX that I am using for hatching. My eggs are on day 21 today. Temperatures and humidity have been perfect the entire time (incubation and hatching). So, I have a confession. Since I am used to my eggs hatching day 19 in other bators, I was getting nervous. I have had 2 eggs hatch already and pips in three more. But, one pipped yesterday and died, so I was afraid the others would die. They have been pipped since early this morning and have made no progress. So, since this incubator will maintain humidity even with me opening the lid quickly, I grabbed one of the eggs that had pipped and pulled off a little piece of shell, to find the chick still alive and a lot of blood. I quickly put it back in the hatcher. Humidity stabilized in less than a minute. My question is this: how many days do I wait? I hate for them to die trying to hatch. How many hours from pip is too many?
