temps verus hatching time

[mechnut450]

on I know if you bake the eggs at set temps they hatch faster or take longer dependingon the temps. I was wondering if anyone ever took thetime and spilt a clutch of eggs and set them so they had different temps and figure out how much faster an egg possible hatch at one temp verus a higher/lower temp?

I know I set up about 88.3-89.5 degrees for my eggs. and figure they go the full 55 days. I also read so many books with so many temp to incubate at i was wondering if anyone had experiment any to see if raising that .5 degree or so avg would make a huge difference?

I also wonder if anyone know about how much the eggs will warm up whe nthey get closer to hatching?? I got a probe right in with my eggs and i will hopefully caught the temp rise. ( this might be a good way to know when to start those famous web cast lol.. )

Tons of other variables exist and I don't think you could compensate for all.

If I was doing the test I would want to have a calibrated temp probe in contact with each egg in the test and the temperatures would have to be logged. I myself like lots of data when doing averaging so I would probably set something up to sample every minute and record the data.

Next would be the tub would have to be exactly identical. While for all intent and purposes sterilite, Iris, or any other manufacturer of the type of tubs we use make tubs the look extactly identical, I have noticed some don't fit the lid as tight as others. Might not sound like much, but this does result in more moisture leaving the tub than one with a really snug lid. Eggs would have to be placed as close as possible to the same point. If vermiculite was used you would have to make sure the depth of the vermiculite from the bottom of the egg to the tub was close to even and the vermiculite went up the sides of the eggs an equal distance. Also each tub would have to have pretty close to the exact same amount of vermiculite with the same water to vermiculite ratio. You could eliminate some of this with other methods, but I'm sure those methods would have variables that would have to be considered as well.

This would be an interesting science project, but not one that I have the equipment to do right now. Also not sure if it would really produce enough information to validate the cost of the study.

My thoughts exactly, too many variables other than just temps. It would be neat to try, though I don't have the time or patience to do it. lol

If someone does try this please post the findings..
