So I took the advice of the folks in the thread and decided to build a mama heating pad for my brooder. I set it up and turned off the heat lamp which immediately lead to them huddling together OUTSIDE of the "cave" and started chirping like crazy. So I turned the lamp back on with the new infrared bulb I bought and they ended up like this. Is this normal for introduction to this new heating pad system, or is there something wrong with the setup? I really want to get away from the heat lamp setup if possible, but it doesn't appear to be working on for me just yet. Also, notice how high I have my lamp compared to the thermometer. It's still reading above 100 degrees, but the chicks appear to be happy with the setup. Should I keep messing with it, or are they fine?
