Hi, I have 2 questions: 1. My 4 girls sleep on top of their coop....will they go inside once the weather gets cold or windy enough? I carried them inside every night when they were new to being outdoors, but when it's their choice, they roost on top. It's been 10 weeks and as cold as 40 degrees, but out they stay. 2. Their set-up is a 4x8 coop inside of a covered dog run. I am getting a pile of poop in the 2 inch space between coop and dog run. I can't reach it to pick it up, but I can sprinkle something on it through the chain link. Can lime be used to dissolve the pile? Thanks for any input!
