Same here. Lock down I think is over rated. I have 3 dozen eggs in the hatching tray and another 10 dozen on the top 2 trays that I turn twice a day. This morning my three dozens began hatching
I've always turned my eggs twice a day. 4am before work then 6pm after work. I've always had a very good hatch rate. Just recently stared to use auto turner. See how this works out.
