If you look on the right side bar of the blog, you will see a link I added for a great chicken coop design resource with plans and lots of great ideas. It was published in 1919. It is called Poultry Houses and Fixtures. Click on the link to download it. It is a large PDF, and I have it on the site for free right now. Because it is in the public domain I am thinking about re-publishing it on Amazon.com, but you can get it for free now.

I have been talking with Bill Keene,who has a site selling information about designing and building your own Chicken Coop. The subject of hot weather and Chickens came up because we are headed to summer. I was concerned because it can get very hot and humid here, so he gave me some advice.
He suggested to avoid big feathery chicken if the weather goes above 100 degrees regularily. Bantams do well, except possibly the feathered feet varities. But here are some other chicken varities that do well in your backyard in hot climates.
