Who was it that put fleece strips into holes drilled in a 5 gallon bucket and encouraged chicks to use it for warmth?

I really liked that idea, so I used some hardware cloth and three old shrunken wool sweaters and replicated the idea.
14 of my JG and barnyard mix chicks spent the night happily in that contraption, as warm as if they had been under a lamp. The chicks are in a brooder attached to the side of the big coop. They've got their own little yard to play in, and lots of FF to enjoy.
So far, so good.
