hi, I have a LG 9200 styrofoam cooler with electronic thermostat. use a water weasel with accurite probe inside. plugged into surge protector. I live in a house with baseboard heat. no basement. I am having trouble keeping the temps constant. it was varying between 98-102 and then spiked during the day at 109 that probably killed these eggs but want to try to get it down before ordering more eggs. this is about my 4th or 5th time trying to hatch. all shipped eggs, about a 20% hatch rate but I always have problems with temp spikes. after much cussing I have finally got it stabilized from noon to 9 pm today by putting it in my shower, smothering it with towels, blankets, sweatshirts, keeping the door closed and shades pulled down. also pulling curtain closed. I've been running only difference of 99.5 to 99.7 since. will see what happens when temp drops tonight. I work nights and leave at 2am so will have good idea of how it will go. ok, so trying to find a better way to duplicate this. don't want to go without a shower for 21 days and only one bathroom. my dad suggested putting the incubator in my oven which I only use twice a year. I use the top every day but not the oven. he thought the oven would be insulated very well because it has to keep the heat in. anyone have any thoughts about this? I will run a test with thermometers to see if using the stove top raises the oven inside temp. another thing I wondered about was buying the old fashioned kind of chest freezer. not the styrofoam jobbies and putting the incubator inside of it. reading online, some claim to keep ice frozen for five days so must be very well insulated. may have trouble finding one big enough. will I have problem with air exchange in it? I know some are converting fridges to bators but wondered about just sitting the bator in an unused fridge and closing the door? (mine died a month ago and will be in my kitchen until spring or at least warm weather to haul off). sorry for the long posts. I've been reading your site for several days about bators and ready to throw this one in the trash but not ready to shell out $200+ for a better one without trying harder. I've had this bator 2 years but this is only second batch of hatching I've ever tried. I got kinda disgusted the first time. the temp swings made for some nasty hatches with chicks hatching but dying shortly after with unsealed navels mostly.
