A heat lamp with a red bulb and a wooden coop my hubby built from scrap is way cheaper...lol
Sure is, but commercial chicken operations operate on a vastly different scale these days. Back in the 1950's my dad went in for "chicken farming" for a while, and we had a few hundred birds (raising chicks to friers), and thought it was a "large scale" operation. Nowadays, a "chicken farm" will have tens of thousands of birds in multiple specially designed "chicken houses". The old story of "get big or get out".
