I am hatching chicks from an incubator for the first time. Usually I use a broody hen. I have a chick that hatched earlier today which is day 18. The egg wasn't mailed it was mine and i took it from the nest box to the incubator the day it was laid so Im sure about it being day 18. Should i leave this chick in the incubator until the others start to hatch? How long should I wait for the others? If they take a few more days should I move this chick or leave her with the eggs? Thanks!
