Today is day 21 and I have two babies They look healthy and are wobbling all over.This is my first time ever using an incubator and I'm a little stressed about the chicks knocking the other eggs around. Will the unhatched chicks be able to hatch alright if they keep being rolled over? I have several other eggs with pips in them. Am I just be overly concerned since this is my first hatch? Or is there anything I should do?
