I built a coop/run that is 5'x10' total. They have the entire 50 square feet as their run and a 5'x4' coop that sits above one end. (I have 4 girls - 2 Buff Orps and 2 Ameraucanas) I can set the coop on my concrete patio where a hottub used to be and put some sort of material in the run or I can put the coop over some red 1" landscaping rocks where a flowerbed used to be. My landlord doesn't actually want the coop out on the lawn. The girls will be let out into the main yard throughout the day but they have to share it with the dogs. How much time outside of the run should I allow the chickens? I don't have the money to fence part of the yard this summer so we will just have to work out a schedule with the dogs. Any input would be greatly appreciated. Thanks
