I have 6 mallard ducks and 8 chickens in a 12by12 pen. At first I had three of those plastic waterers, but the chickens would practically fight over a place at one of them and my ducks would get the disgusting and bring mouthfulls of food over and clog up the little holes. So we put a plastic baby pool in too ,so now there is more room and the ducks can go swimming if they get hot (we live in Louisiana). But now the ducks STILL clog up the plastic waterers and they get the pool water so dirty so quick that I have to completly take out all the water and scrub it down to get all of the *cough cough* mud off. And thats not easy, because i cant just dump it out right there in their pen. I have to scoop it all out with a bucket does anybody have a easy cheap solution please???
