This is our first "go" with chicks. After many hours of researching brooder ideas, we decided to use the dog crate and heating pad concept. We brought our little girls home yesterday. They love their new home!!! I placed the heating pad on a cooling rack and covered it with an old towel covered with Press N Seal. I suspended it in the corner (for stability) with chains and key rings and small carabiners. Adjusting the height is so easy.
