I just put my heat lamps on a timer so i dont have to remember to plug them in and unplug them. Mine are using their brooders for cover in the run til i get up the nerve to integrate them with the mature hens. Since that's the only cover they have i have to turn the heat off during the day.
This is,my first flock. I have the lamp off at night now. I think they could probably go out full time but the bottom of the run doesn't have any protection. Their brooder is only a largeish dog crate in my living room. Tell ya what though, I'm not doing chicks inside again if I can help it. Dust is everywhere! Lol
