I just set up my brooding "facility" in an unused bathroom. Lined the tub with plastic (taped all edges), newspaper, and old towels for first few days. Hung a 100W incandescent bulb with shop reflector about 18" above and temp went to 100. Had to move it up to about 2.5 feet to get temp around 95. This means the whole brooder is about the same temp & light. Would it be better to have a lower watt bulb hanging lower, so the heat & light was "closer" to the chicks? Would this allow them to get OUT of the heat & light when they want? Right now the brooder is draft free & right temp, but constant temp. throughout. Thanks for help, chicks coming day after tomorrow!
