My husband brought home a LG incubator and turner from a guy at work for me to try. It has no instructions, he got it used so he has no idea how it works. I have just a few questions: 1. are the air holes just the little tiny ones on the underside and top, or are you suppose to open others? 2. I turned it on and got it up to the right temp. but it has a very funny odor, can odors hurt your hatch? I did soak it in the tub after id unhooked the heat element and removed all electrical stuff, then put it back together.) 3. Does the motor on the turner get hot, or maybe its just the incubator temp. that makes it feel very hot to me? (just am afraid it might be bad as it seems pretty hot.) 4. How much water do you add for humidity, I put just a little and it jumped to 65%? Thanks for the help, I am kinda scared to put my eggs in the incubator since the cooler bator I made seem to work but have a staggered hatch about to happen so I figured I would try this out.
