I got the bug and decided to build a coolerbator. This will be my first time incubating. I made the light bulb/water heater thermostat version. I may have damaged the thermostat when modifying it. When I tested it thoughI was getting 4 degree temp swings minimum so that wasn't going to work. I ordered a cheap digital controller the MH1210 off ebay and while I waited for that to arrive I scrounged up a crock pot element. I did add a strip of aluminum foil along the cage so the heating strip wasn't blasting the eggs directly with heat. I was dreaming of an elaborate turning system but found when I put an egg carton in, it sat at almost the perfect tilt so I'll just spin the cartons around. I punched a pencil sized hole in the bottom of each egg pocket so their is air flow around the bottom of the egg. I'm really Eggcited about the eggs I got. They are a barnyard mix but one of the roos was a beautiful blue arucana and some of the hens were arucana as well. I should be able to separate the blue eggs and hopfully get some pure arucana as well, EE's at worst. The other roo they has was a jersey giant so hopefully I'll be able to separate them young. I set eggs on the 7th and spent two days tweaking it. The digital controller's logic is sort of odd but I think I have it worked out. I'm getting a temperature gradient but right now it seems to be holding at 99.7 on one end and 101 at the other. Humidity is holding at 30-40%. I'm shifting the cartons so they cycle through the zones. My fan is not super strong or I haven't figured out the best position for it, but for now everything seems to be holding temp but I don't know how well it is circulating. The fan is pointing strait up at the lid blowing over the heating strip. I will update as I go thanks for checking in.
