It works for you so that is awesome, keep it up. What works for you may not work for everyone. I have been raising chicks the same way for the last 10 years and have yet to come up with a maladjusted stressed chicks that fails to thrive and grow, when or if I do Ill think about trying to change somthing. You cant compare chicks to people, my chicks fall alseep and stay alseep just fine with or without the light, I however wouldnt be able to sleep in 95-100 degree temps no matter what color the light. They dont all sit directly under the light, the cage is much bigger than the suface area of the light and so they have super warm spots directly under the light and lesser so as they move out somtimes they are under sometimes they are out walking around.
I have tried the red lamps before unfortunatley they just didnt work as well.
