I had my first group hatch last week. I incubated at 99.5-100, locked down at day 24, and the first one hatched on day 25. The other four all hatched on day 26. This was my first, so not certain it is the best method, but it hatched 5/7 eggs that went into lockdown. There was at least one day that I found the incubator had crept up to 101, which might explain the earlier hatch date. I kept humidity at what I hatch chickens at. I gave the keets away to a friend, but she says they are very healthy and doing great. Maybe someone else more experienced can comment on their methods. Good luck!
