I am on day 18, so i have just stopped the incubator from turning, taken out infertile eggs, put water in both pans and blocked both air holes. The user guide for my incubator says to do this, but also says: Caution: excessive humidity can cause problems! The air pocket in the egg should occupy between a quarter and a third of the egg at time of hatching. If humidity is too high, chicks will be wet and sticky and the air pocket too small leading to death 24 to 48 hours before hatching So i am a little confused - can i have too high humidity? is 100% going to cause issues? I have kept humidity stable until now, but not totally sure of keeping 'high' humidity but not 'too high'
