I actually read this article before and incorporated several of the ideas and they work fabulously!!
I built a brooder box with the sides covered with field fence. Field fence has larger rectangular openings, the chicks could easily go through the spaces, but adult chickens can not.
I used a heat lamp, because I could not find a heating pad that did not have an automatic shut off. The chicks thrived and had no problems integrating with the flock.
I have been brooding all of my chicks out in the coop since then. It's the next best thing to broody raised chicks!!
Your article is very well thought out and written. It makes me wonder if you were an English teacher

Thank you very much for such an informative article!
