Hello! I am an American expat living in the south of France. We have 3 beautiful girls that lay wonderful eggs. I am in the middle of building a coop for them and want to include a poop board under their roost. We don't have Sweet PDZ here in France...is there an alternative product that can be substituted? Any insight would be greatly appreciated...it is very hot here in the summer and I am guessing that our coop will be very smelly if I don't find a solution!
