So sorry to hear that OES, I am by NO MEANS an expert, but if it were me I would try a couple things: 1. Try to find some local white eggs from a farmer that has a good many roosters running with the hens. With white eggs to start with, then get a good bright torch and get a candler made. With a good candler made, and white eggs, you can start to watch the egg develop, veins and all, and get an idea what is going on inside the eggs. 2. . Try a dry run of your bator for a few days, with a couple quarts jars of water it there as heat sinks, to see if that levels out your temps, Don't try chasing the temps around with your wafer, just leave it in one spot and see if it levels off and stays one temp for a few days. Place your bator in a room where the temp stays as constant as possible. 3. If you find that it stays the same temp for a couple days, then you can start adjusting wafer. Give it a few hours after each adjustment to see what happens. 4. Once you get the bator set to a good temp, and holding there, put in your eggs, take out the thermometer, and do not touch the wafer again. I am always tempted to start chasing the mercury with the wafer if I leave the thermometer in. 5. Leave the bator dry for the first 18 days, then add some water in the trays, or a wet sponge (Warm water) lock the thing shut, and go on a three day trip somewhere! Many of these suggestions may seem crazy, and your results may vary, they are just what have worked for me. Most of all, Hang in there, keep trying! Jim
