Needs quite a bit more explanation of how to build this.
Take you 4x4 and build your frame. However, no explanation on how do I build it?
Attach your floor to the legs. But how did they attach them?
How was the lamp mounted and to what was it mounted to?

The pictures were beautiful and can be useful for brainstorming. However, as far as being an article that claims to explain how to build this brooder, there's a lot that was left out.
Sorry to be so blunt, but safety is important to me. The hardware cloth should be covered on both ends so that no one can cut themselves and the "water thingy" should be modified to prevent drowning. Also, though the words of the article were adjusted for pine shavings, all the pictures encourage splayed leg.
Lastly, this is not step by step, but more of, milestone by milestone.
