As a rule I don't add humidity until day 18 as someone else suggested so it running 20% this time was just from the room humidity itself. I just read the book again and it stated to remove the red plugs for hatching, I haven't done it before, but should I have done that? Last year I didn't have problems except for my errors on hatching and pulling out the chicks too soon and the humidity dropping at the end.
Any other suggestions out there.
I am using a still air with a turner this time compared to egg carton method last few times.
