ha ha that's why the poor shaking little half naked chicken in my coop gets a nice little hotel room with the heat lamp...all to themselves

i totally agree, putting a heat lamp up in a pen of birds is next to useless....are those mute chickens naked now? wow. they evolve fast! ;-P
a big sunny window facing south in the coop in the winter is much more productive-let the sun in and let them soak up some rays.
