If you are going to build and you have the space, why not make it as roomy as possible? A little is good but more is better when it comes to housing livestock of any kind....freedom of movement, space to occupy theirselves instead of picking each other's feathers off, room to get out of a dominant hen's way without getting the head pecked, room to scratch, fluff or otherwise work up any deep litter, a place to put their feeders and waterers if you need to do so, room to fence off space for a bird that needs isolation, etc. All these things make a chicken's life better.
