I don't understand. From what you are saying you do lock down. Do you open it during the last 3 days or do you wait till you chicks are hatched? I think the method that I used this hatch would be considered not locking down. Neglected to write down which day I set, never added water and didn't...
I did today, only.problem is the turn is still in the bator. I forgot to write down the date as I have 3 hatches going on. I guess the way you do it is what most on here call a dry hatch and lock down. Is the last 3 days, you remove turner and bump humidity. WELCOME TO BYC.
