I am planning to start construction on my first coop in the next couple of weeks. My initial plans are for the coop to e 8x6, tall enough to walk inside of. I plan to have the run off of the 8 foot side so my run will be 8 foot wide. I will probably go 12-16 foot. I am only planning to start with 6-8 hens. I live in Indiana so the weather is never reliable, we could have drought, or record rains. I have five acres of yard so I have plenty of grass clipping, leaves etc. Is there a huge downfall to letting the run go to dirt and then just throw in some grass clippings etc routinely. I don't want to have to keep it full of sand, pea gravel, etc unless it is really required for some reason. I do plan to let them out some when I am home in the evenings but the majority of the time they will be confined.
