It is my first time hatching eggs. I only have 4 eggs in the incubator. I did the dry hatch method. The humidity has ran at 19-20% pretty much the entire time.Tomorrow's is day 18 so we will be going into lockdown. I candled 3 of 4 eggs and all have movement and look good. The 4th is a dark egg so we are just hoping for the best. I have read that I should slowly increase the humidity to get it up to around 60% and I have heard to just leave it and the chicks hatching will automatically raise the humidity. Any suggestions? Or maybe just raise it to around 40%?
