I bought an incubator combo kit from incubator warehouse and this is my third one. I keep sending them back and they send me a new one saying that I must have gotten a defective one. I have a homemade incubator but was wondering if there was another way to incubate besides with a light bulb. I have to switch incubators to the one with the light bulb because the kit keeps going out. And when I switch incubators I usually wind up with none hatching. The last time I lost 28 eggs.
