I put my duck eggs in lock down yesterday about 3pm. I have LG Bator forced air. I had 1 plug in & 1 plug out till lock down. Now Both plugs are IN. I Did have Paper Towels under eggs(as I also read in a post) but then some one responded in a post to me saying, not good to use paper towels cuz they slippery or what ever/ ducks legs to weak. I couldn't get humidity up so also figured the paper towels had some thing to do with it. So I removed them & laid eggs in bator on the wire bottom. I have a small(not to small) container with a sponge & warm water in it, in bator. Another wet/rung out sponge laying in bator. I Filled the channels in bottom of incubator with warm water.I couldn't get humidity up enough(I needed 80-85 humidity) so I was told to add a damp wash cloth to the container of water but 1/2 of it hanging out of container. Put container UNDER a vent hole so if you need to add water you do it through the hole in to container. This worked good to get humidity up to 80-85 It actually made most of the water disappear from the container. But DON'T PUT Bator on a Good Table WITHOUT a Bunch of towels UNDER it. My bator has holes in the bottom & the wash cloth hanging out of the container/water acted as a siphon wick & the water went in to wash cloth & drained from wash cloth to the bottom of bator then out the holes on to the 2 beach towels which I have under the bator. I added warm water but it was more like on the hotter side not just warm. the temp jumped but only cuz the themometor was right by the water I just have to watch & monitor the heater a little bit some times. what ever you do just have every thing ready and prepared so when bator is opened it will be Quick. add small amounts of hot/warmish water at a time, give a little bit of time to let the humidity rise and temp. I hope this helps i know how it is when your asking questions & nobody seams to be responding. ~ Good luck, Julie
