Different hens' egg's

[hillbillyhero]

This is my first time hatching out of an incubator. I placed two dividers in the middld because i had eggs from 3 different hens. The eggs in the moddle section began hatching two days ago but the eggs in the left section Are just now starting to peep. The far right section i havent heard anything yet. Is it because the eggs were from different hens or what?

Welcome to BYC!!

So the eggs were all set at the same time, correct? Have you done any candling along the way to verify that the eggs were fertile and were developing? If so, during the candling did the groups seem to be developing on track with each other?
ETA - how large is the incubator? Where in the incubator is the sensor(s?) for temperature and humidity readings located with relation to the various groups of eggs? Depending on the incubator it may be an issue of inconsistent distribution of heat causing variations in the rate of development in the eggs (similar to how eggs in a large clutch under a broody hen can have variances depending on what part of the clutch an individual egg is located)

Thanks! Yes they were all placed at the same time and i candled them after 14 days and some looked darker than others but they all were pretty close to being compmetely dark. The ones i could see completely through i took out and one cracked and oozed so i threw it out. All the eggs from the center have hatched. Still just those ones on the left peeping. I understand some will come a day later but i am just curious if it is happeneing like this because they are from different hens
