I'm certainly no expert since I am raising my first batch of chicks now, but I think you could get away with turning the light off altogether during the day. my chicks are 5 weeks old today and they have spent the last few nights outside with no heat source. Temps are down in the low 50's at night here. They seem to be doing just fine. Good luck!
