I have previously used my incubator on 3 batches of quail eggs.. The first time I didn't have any problems, the second time the light would cut off sometimes when it was tapped. And the 3rd time (the eggs never started to develop, they were some of my birds first eggs) the light did this thing where it was only half way on.. It kinda reminds me of the long florescent lights that buzz and don't come on all the way. I just bought some more eggs and they were shipped Today so I am trying to calibrate the temperature and humidity, I replaced the light socket but it still does the same thing. Just not all the time. You can see my set up in this picture What do you think the problem is?
