I am planning to start my first small flock this Spring. I live in Missouri, where our temperatures vary from below 0 sometimes in the winter, to over 100 degrees in the summer. My coop will be about 6x4, and my run about 6x10, plus I plan to use a 6x4 mobile run a few days per week (that will fit on my garden beds!). I am thinking of a Buff Orpington, a Partridge Plymouth Rock, a Dominique, and a Delaware, all of which I can get from local hatcheries. I am most concerned about the Delaware, as the climate listing on the breeds page says "heat." Would a New Hampshire Red be a better choice?
