with 100% success. use a lot of medium, so that the heat from the hot spot gets more diffused and evenly spread out, and use plastic egg crate as well to further help diffuse... an added benefit with egg crate is you can have a higher humidity without eggs contacting moisture... and you'll still need to cover the top to hold moisture or it'll dry out and become unstable. plexiglass sheets work well. saran wrap will warp down and throw moisture onto your eggs and screw them up.



this is why an adult rack works better, plus a hatchling rack is too small for decent size clutches. but for small clutches, it does work - IF done right.



but TEST first. set it up and let it sit for a few days to get everything evened out and into its normal state - then put little sealed water bags (these are your test eggs) exactly where you plan to place the real eggs. you must use an outside thermometer probe in these cases (on every clutch), stuck smack in the middle of the clutch cranny to register and watch that it stays at 89%. its ok if the egg closest tothe front is 88 and the one towards the back is 90 - but use a good qua;ity temp gun to check on them once in awhile to make sure there is not too big a spread on your temps.



you can see this way is more work and worry than one good big incubator with constant even temps throughout. but these racks work in a pinch. but you must be vigilant.
