so i live on a hill, my duck pens on a slope and i do everything possible to try and not let things get muddy in the pen, but when it rains, its terrible. i practically fall on my butt because of the slope of my yard... its a catch 22 considering it helps wash all thier crap down the hill.... my question isssssss has anyone heard of that plastic driveway stuff? like rubber mats with holess? see here some examples: http://www.boddingtons.com.au/civil/grass-reinforcement-parking-mesh.htm http://www.polymax.co.uk/acatalog/Polymax_Grass_Reinforcement_Mesh.html supposedly grass grows over the product, its like an eco-driveway that you can have grass and drive on it.. im wondering if this product could be used to keep grass alive in the pen?, and also there are some that say they have good drainage so it would be easy to clean and drain away easily.. can car traffic compare to duck traffic? lol I really really want grass in my duck pen! any ideas guys!?? and by the way if anyone in the RI, MASS, CONN area is looking for any ducks (practically adult).. i may be looking to sell (or gift) some indian runners, i have 5 and now have ten after my broody layed in the spring I have too many, just cant bear to let em go but they are a handful.. havent decided if i am parting with just the two juvenile males or all 5 of my juveniles, which is two males and three girls...ahhh i dont really want to... but i should! thanks for reading!
