I have tried other bulbs and 15w doesn't hear enough and 25w over heats if I hook my fan up(recycled laptop fan) 25 isn't hot enough anymore. I taped half my big hole thats on te back and opened a smaller hole on top. My humidity is rising and my temp is still right around 99-100.
If you haven't got your chickens yet there are 2 great places fairly close that I will recommend Esteshatchery.com out of springfield and impeccable poultry on Facebook out of Ava.
My temp has gone up and fluctuates between 99&100 but now my humidity is not going above the 40 the picture shows... I know what the temp\humidity should be at but what are the absolute minimums I can use.
So I made an incubator out of a styrofoam ice chest for my duck eggs, I have a 23w compact fluorescent bulb as my heat source and this has been my best bulb yet (15w was way to small, 25 too hot and 40w was gonna cook my ducks). I have my humidity under control but my temp will not go above 97...
