I miscalculated my days and locked down on day 19. My temp was at 100 and humidity at 45- 50% humidity the first 19 days. I have a split hatch so I candled and moved the lockdown set to my hatching incubator. There was good movement, air sack looked good and the incubator was holding at 100 degrees f and 65 to 70% humidity. I am hoping this does not hurt this set.
