You need to provide a little more information, as well as some pictures of your coop, and grounds.
It is also a good idea to provide your general location, so we can give better advice, based on climate.
In general terms about smell.
It will be minimal if it is kept dry. That means a well ventilated coop, and rain proof.
Well maintained, and litter removed, and replaced with fresh, as needed.
Keep soiled litter, and other composting matter as distant from your desired area as possible. If not possible, then consider throwing into trash collection in plastic bags sealed.
