I have another thread on fixing up an older incubator, but right now am scrambling to get something up and running PROPERLY..I have eggs coming and am panicking.. I was going to phone and cancel, but the number disappeared and cannot find it!!
I have a fridge that had been used as an incubator, but after much scratching of the head, trying to figure the problems of terrible hatch rates out,
have decided that the fridge size is w-a-y too large for the digital heater that is in it, and simply cannot keep up.. and the corresponding issue of trying to get the humidity levels up to proper levels in a larger space is not working.
I have a much smaller fridge that I am thinking would work much better, however I am concerned that if I put the heater in the top--pointing down_-- like I did in the larger fridge it might be too close to the egg rack even though I would put fans on the side to blow the heat sideways and then down to the lower racks. I am afraid it is too close and might cook the eggs...
. i could put the heater on the side at the top- blowing sideways----instead of the top pointing down on the top rack- with extra fans to help circulate the warm air.. around and down to the lower levels..
I placed a egg rocker with a very large duck egg and measuring tape for comparison to the inside of the top of the fridge. ( I would take the top grating out also..
- I have not seen the inside of a commercial incubator to know how close the top egg rack is to the heater in the top.. Is this too close to the heating element and would it cook the eggs even with fans blowing the air sideways??? Does anyone know??
or would it be better to place the heating element sideways in the top of the fridge with an extra fan to blow over the top of the eggs?
Or would it be better still to place large bolts sticking out inside the fridge further down inside the fridge to hold the rack and ,move the eggs down a bit?, instead in the "slide" for the rack and give more clearance between the eggs and the heater ?? Anyone know how far down from the heater to the top egg rack in a commercial incubator is?
Any advice would be appreciated..thank you very much in advance!

Hmm. Unfortunately, I don't know the specs of commercial incubators nor do I have familiarity with that heating element. I use 45w bulbs in my cabinet incubator. Generally, with standing models, there is a vent running down the back blowing into the bottom of the incubator so that heat is spread out more evenly instead of remaining near the top, with a baffle installed in between the heating element and the eggs. I have some pictures of that setup in the article link in my signature.
 
Bantychooks-- I cannot get anything when I click on your username.... nothing like any pictures or anything......
 
I did a re-measure, and found that the egg turners are 1/2 inch too big, grrrrr, so I am back to the "fridge bone yard" ASAP--thank you all for your input!
