My 7 chicks are 2 weeks old today. I'm brooding them in my garage where I'm having trouble keeping the brooder temp around 85 degrees. Now I need to drop the temp to around 80. Is it ok that I turn the heat lamp off at only 2 weeks old? My brooder is 6x4 so the chicks have plenty of room to get away from the heat lamp and none of them seem uncomfortable at all. I don't want them to get spoiled in a 85-90 degree brooder when I go to put them in their coop in a couple weeks. I'd appreciate any advice...thanks!
