What Cheyen said was exactly what I was going to say. Don't raise the lock down humidity for the buttons so high. Maybe half of what you were going to raise it. The buttons should be ok and it shouldn't hurt the valleys either. You might delay the raising of the humdity for the valleys a bit, especially if the eggs are not pipping on Sunday. If the Valleys are pipping, you will have to raise the humidity up more. If the eggs are not pipping on Sunday, don't raise the humidity til Monday. Use your judegement. Good luck with the hatch!
Edit to add: I think I said that wrong. I am still asleep. LOL You can up the humidity for the Buttons a bit lower than you normally would, so you don't drown the Valleys, but come Sunday you can crank up the humidity for the Valleys and the Buttons should hatch ok.
Very confusing this early in the morning. LOL
