Insulation will keep the cold out but it will also keep the heat in.
I don't think that insulation is a MUST HAVE sort of thing.... as long as you don't care what your heating bill ends up being from running a lamp and then having all that heat escape into the great outdoors.
And if he decides that running a lamp isn't necessary either then hopefully he has enough chickens to provide a fair amount of body heat for each other and keep the water thawed. Chickens can handle cold pretty well, but may quit laying as they reserve their energy.
I'm an egg hog, so I chose to heat my coop, and it's insulated too, but it still averages around 15F through the winter.
True, wild birds don't live in insulated houses, but you don't see wild birds flying around this neck of the woods in the depths of winter either. They're tucked away into their cozy little tree holes, reserving their energy and trying to stay alive.
To each his own.
