HI All- I am planning on getting up to 8 egg hens this spring. I have read a lot of differing recommendations on coop size, so I thought I'd ask here. The coop will have a run, and it will probably be about half covered. We plan to free-yard them sometimes, but are not sure how well that will work out and the frequency, but likely a couple of days a week. So for 8 hens, how much coop space, how much run space? I was thinking a 5 x 5 coop, and a 10 x 5 run. but that seems small. Also, what are the pros and cons of a coop that is up in the air, vs having the floor on the ground? I plan to have a droppings collection below the roost area, and deep litter in the rest. Lastly, I'm really interested in the highly ventilated systems, it sounds like a lot of venting up high is good, and be able to close it for bad weather. I live in Montana, but our winters aren't terribly bad the whole season. Also big windows down at the roost level, with hardware cloth for summer ventilation. Thanks!
