Still in the planning stages here -- we haven't closed on the house, for one thing. But my plan is to have 5-6 layers (I'm thinking heritage RIRs) and a pretty big run. I want to lay down a big base layer of hay and straw and start composting everything I can right in the run, so the girls can forage and poop and turn everything into black gold for my garden. My question: how big a run should I plan on for this? I know what the regular minimum is per chicken, but it seems like with all this composting going on, I'm going to need more space. How would I plan for that? I'm sure this has been covered somewhere, but I can't find it (bad Google-fu, I guess). If it matters, note that this is New England, which means fairly high humidity and quite a bit of serious cold and snow during December-March. Again if it matters, the main points are eggs for my family, compost for my garden, and some chicken TV to amuse us all.
