How big do y'all think a coop should be for 12-14 ducks? And what do y'all think of putting hardware cloth as the floor so the droppings can go through and onto the grass o should I have a board as the floor? And what about putting chicken wire all around the coop? I want to make it portable kinda like a chicken tractor. I'd use it to put em in at night and let em out during the day. Let me know what you all think Thanks y'all. Ivan
