i use that same incubator so i understand what you are talking about. as long as you are seeing veining and movement, you are good. did you do a temp calibration? and hygrometer check before starting? depending on where you live and how accurate your hygrometer is, 50% may be a little high prior to lockdown. I try to keep mine around 30% until lockdown and i don’t add water until it falls below 20%. i got 4/6 healthy hatch on Halloween chicks, 10/17 hatch on Thanksgiving quail, and fingers crossed for 8/8 that are in lockdown!!yes my humidity is aprox 50% as i was umming and arring on what was best i top up my water 100mls every couple of days i have a joneal12 incubator
