I made an incubator with a styrofoam cooler and a 25w bulb with a dimmer. Problem is that ever since I started it. Firstly it had no holes on it (the cooler). But I noticed the humidity wouldn't go up (with a small cup with water inside), so I changed it to a bigger container. Thing is that it didn't change. So I made two holes in the top of the incubator. And the humidity raised, but here is when the temperature problem started to chase me. When the tempetrature stabilized on 99.5 F I put the button quail eggs inside. The first day the temperature stayed pretty fair. But each day that passes is more cooler, so the temperature lowers to 98.3, but then ups to 99.0. I didn't worry much about this. At night I have to raise the intensity of the light bulb with the dimmer to increase the temperature. Yesterday I raised the intensity and temperature increased up to 102.5. I am really worried that the little chicks were affected. What recomendatios would you give me to keep the temperature safer for the eggs? (The eggs have been incubating for 8 days now). I have seen some growth in some eggs that are a little bit paler than the others. The little chick takes up like 75% of the egg now. I don't want them to die, they're the only hope I have to reproduce my button quails, since the male died the day after I put the eggs inside the incubator. Again: What recomendations would you give me to keep the temperature stable?
