Yikes! We were all beginners at one time and surely aren't know it all's. To explain lock down better, it is on day 18 of your hatch sequence. You remove the lid and take eggs out of turner trays and arrange on bottom of wire mesh that covers your water. To better that, go to a arts and crafts store and purchase some felt in 8x12 sheets. Fit to cover the wire mesh. On day 18, fill an old windex bottle (Well Rinsed) with water and spritz the felt as if to moisten or slightly saturate it. Refill your water slots as well. Now arrange eggs on felt. They don't stand up, so you lay them on their side! Ha. Put the lid back on and heat will slowly return to the setting you are working with. You might have to tweek it a bit after an hour or so as it may have changed a bit. Take a deep breath and relax. Any more help we can offer?
