I have 6 baby chicks in a brooder i made from a clear tube. They just turned 5 weeks old today, and they haven't gotten all of their feathers yet they are still growing. The lady at the store said their temperture should be between 70 and 75 degrees in their brooder. Well with their light on and this summer weather in our house the temp. with the light on floats between 80 and 101 degrees. Am or should i just turn the light off and let them be in the dark? Would that be okay or should i keep it on, I dont want to roast them.
