My chicks are due to arrive at in a couple weeks. I live in a cold region and by the time they are ready to go out it will be 40-50* day time and 25-30 evenings. I dont have a garage or similar cool area to keep the brooder in. I do have a spare room that will be dedicated to them once they arrive. My question is do you think I should keep the room temp cool, ie' shut off the heat vent to the room and keep the door closed? Coldest it would probably go down to would be 60 I am guessing, or I could open the window slightly from the top ( not a draft danger it would be high and away from brooder) to make cooler.
