I have a broody hen that hatched out 2 of the four eggs she was given. I collected the other two and pht them in the incubator (already running for a different hatch) and candled them this morning. One is not as far along as the other, but still moving (I only gave her three...someone was sneaky), the other looked to have pipped into the air cell. Looked in on it this afternoon and it has externally pipped. I understand that it can take some time, but my main concern is the humidity level and the other eggs. It is currently around 55% on day 15. Will this be high enough for the hatchling? I have 12 other fertilized eggs that are progressing well that I don't really care to sacrifice for one accidental pullet egg, but if I can make it happen with mininal risk to the others I would like to try.
