Thanks, I use a 40 watt bulb and a red 60 watt bulb in the brooder. The digital thermostat from incubator warehouse, axial fan and heating element keep things exact for temps. The two zip ties hold the temp probe to the piece of wood that's in the center of brooder. The plywood divider that's mounted to the right of waterer can be moved out to the 6 foot wide point to give room to the chicks as they grow. Don't like the heat lamp that I was always messing with throughout the day to get temperature close.
I built the incubator shown over last winter.
