I have eggs in my incubator that I set on Thurs AM. I'm using a LG 6200 Still Air Incubator and this is my first attempt at hatching eggs in an incubator. I've seen a couple of posts recently about using shelf liners. Could someone explain this to me? The specific questions I have are: 1. Could you use a shelf liner during the entire hatch? I'm having a hard time turning eggs without them rolling back. If I could use a shelf liner it would provide more traction and I wouldn't have this problem. 2. Does the liner reduce the amount of humidity coming from the water below? 3. Should the liner be the rubbery type (don't know how else to describe it)? 4. Is there any other info I would need to know about using one. Thanks for any info!
