Homemade Egg-o-Meter Works!

Regarding temperature inside the egg vs air temperature inside the incubator, you MIGHT find this posting somewhat interesting:

Some differences in "embryo development" have been observed in a controlled experiment regarding temperature in the last part of incubation.

MIGHT be worth looking into.......

I dunno,

CYN, I am going to have to do a little checking on this devise of yours. Cbiblis had built the very same thing as you described and for some reason or other, he took it out of his bators. I am thinking it had to do with temperature control, the silicon egg would read temps as you described, but it took longer between the heatup and cool down cycles to register a change in the temps. In other words, it works, it was just slow showing any actual change in the temps. Anyways, he changed to something other than silicon as the filler for the plastic egg and it seemed to work just fine. I'll try to find out what material he ended up using or if he just scrapped the whole ideal.
 
Deciding what to put in mine was hard. I dont think I have any hair gel here. I do have some aloe sunburn relief gel. Thought about gelatin, but DH wasn't sure about that, being a food product. Anyway, that won't be the main thing I use for measuring temp. I do think that it takes a bit longer to heat up than an egg would, but it actually seems to cool down fairly quickly when the air temp drops.
 
Actually, the gelatin might be just the ticket. If you consider that gelatin is just groundup animal bones, the temp variations might be more in line with what a egg would experience. Might get a little messy though, and could possibly spoil. Maybe use a ballistics jell.

Anyways, after reading the link that Junkmanme posted in his other thread, this is something very much worth considering.
 
Yours looks better than my jar of kid's Flarp, duct tape shut... LOL. But it is a better size than my water wiggler was. I was considering doing this, glad to know it's going well.
 
my husband created the very same thing using a plastic eggs like yours and filling it with, of all things. hair gel. - small hole in the end to insert the probe. and It seemed to work great on our last hatch, and it's now in use again for a hatch we just set tonight. Of course its not our only temperature reference in the bator.
 
Cynthia,

CONGRATULATIONS on a successful project !!!

I would like to build my own "Egg-O-Meter" also. I don't know WHERE I might find a plastic egg to use.

Anyone have suggestions on where I could locate a couple plastic eggs?
