I washed out my hatcher yesterday and let it sit in the sun yesterday/today...now I'm trying to get it set up for my next hatch this week (only 2 eggs survived out of this one up to this point. 8 were shipped-4 were broken when received-2 scrambled by UPS... but these 2 have been growing well since...) So anyhow, the one thing I'd like to change if possible is the babies feet getting stuck in the metal mesh on the bottom of the hatcher. I'm also concerned by sharp edges etc. I was thinking about how so many people recommend using the shelf liner in the brooder....well why not the hatcher/bator as well! Here's how I have it set up now... Here are the pros I can see: -Protects tiny feet -Protects new babies from sharp edges -Gives some padding when they first fumble around. -May keep eggs from rolling around as much. -Help with clean-up...yuck! Cons: -Possible toxins from this stuff being warmed up (but does it really get hot enough for that to happen and it's almost the same temp in the brooder...) -Could it possibly retain moisture/heat? And that's really all I could think of for cons...does anyone else have any ideas? I have the hatcher warming up right now.
