If I use a Poultry Netting or Wire Mesh as the floor of the coop. I was considering it~ I am not out in the rural woods, I am an urban backyard chicken keeper! So I don't know that I would have alot of predator issues. But I would still want to make sure it's secure from possible hawks or racoons. I was thinking of building a box below the coop and filling it full of sand to catch the droppings for easy cleanup and recycle it to my compost. Granted in the winter I would probably find a way to cover up the bottom by making a slide in peice of wood to block out the cold. I'm toying around with the idea and wondering what the good and the bad would be from doing this. Also with this heat we are having during the summer it would be even nicer to have that draft. Then there are other thoughts as to the outside conditions like storms, rain would the moisture in the air or wind from the storms be an issue for the hens when they are inside?? Any thoughts and opinions are welcome!
