I am sorry about the bad luck! I use the room humidity method. Which is I don't worry about what the humidity is until lockdown. I should not say that, I have mine set to not go below 30%. It is humid here so I usually don't have any problems. During lockdown I bump it up to 80%. That way if they pip early, there is usually enough moisture til it hatches, and they don't drown because the white disapated. That's what works for me, you could try it, but I don't know what kind of bator you are using. Good Luck
Thanks I will try that. I am using a hovabator.
