Spy, I'm not depriving my chicks of anything. They are babies, they sleep when they want and they eat when they want. Often during the night I check on them to find them all asleep so having white light all the time does not deprive them of sleep. As my brooder chicks grow up they don't have neurological problems. When I put all my chicks together as teens there is no difference between those who began life with daytime 24/7 and those raised by their mothers outside. I know I wouldn't want my birds to enter life with rose colored eyeballs.
