Rest in Peace -2017
I was not understanding how your brooder was constructed. Of course it's not going to get warm, it's made entirely of wire. There's nothing to hold the heat in, it's going to dissipate into the room. You're heating the entire space the birds are in, not just the brooder. Try getting a floor and some walls and see what happens. I brood in a large galvanized metal livestock trough and one big red bulb at the height of the edge of the tank is plenty of heat. You need to contain the heat you have, and lessen the amount you're putting out.
