Hello everyone! I am new to raising my own chicks but have hatched several dozen chicks for my 7th grade students to watch out of our schools Petersime Model 1 incubator (we got it from the Army Corps of Engineers when they decided to stop manually hatching the endangered Least Tern and Piping Plovers). For some reason (not sure if one of our older high school students messed with it or if there is some sort of electrical issue) it keeps getting too hot (about 115) and we cannot open up the vents any farther to cool it down. My co-teacher and I accidentally poached some eggs when we realized that the thermometer gun we were using was giving us a temperature that was about 10 degrees off (darn you Snap-On!!) so instead of 99.5 it was over 112. So...I ordered replacement eggs thinking that we would have it figured out by the time the chicks got here for next week....we still don't have it figured out. Do any of you fantastic chicken-people have any words of advice for me!? We have this awesome incubator that we know can work fantastically but for some reason (now that I want to start my own coop) it has decided to go on the fritz. Any help would be great!!!
