Like the title says, can you use something other than a light bulb to produce heat? I have two heat packs in my brooder now, thanks to the power outage, and they seem to enjoy these better than heat from the light. I was wondering if I could use an under tank heater or flexwatt heat tape to heat my brooders instead? They'd obviously be on a dimmer to control heat to avoid from cooking everyone. If I can use flexwatt instead, then I can set up more than one brooder to keep smaller birds away from the larger birds, plus I wouldn't have to be concerned about other critters getting TOO much light, plus the fact that it would make it so much more organized to have a single shelf in a rack system for brooders, and use a heat tape instead of having to have a big, ugly, bulky clamp lamp. Anyone have any ideas on whether or not this would work?
