As long as the poop is not going into the nests, it’s a good way to utilize space. You have a droppings board so that will work fine. My brooder is built in under my roosts with the top acting as a droppings board.
We all develop our own routines as to how often and where we clean. With my set-up, climate, and number of chickens (which affects poop load) I clean less than once a week, sometimes much less, and don’t draw flies. Some people clean every day. You’ll need to develop your own routine for how often you clean.
