You may want to rethink a brooder inside the house. It may seem like a good idea but after a week you will be contending with the smell and a layer of dust forming on everything. Our brooder is in the garage. A large brooder area (3x4 or 4x5 ft) is nice to have with the brooder lamp near one of the corners. This gives the birds the ability to huddle near the lamp or away from the lamp if they are too hot. You will want a 2 to 4 inch layer of pine chips for the floor bedding. A couple of feet high for the lamp will be fine and as mentioned.... you can replace the bulb with a lower wattage each week as the birds grow or raise the lamp to reduce heat.
