I love my ducks who are now almost 6 months. I am okay with the cleaning their pool, fresh drinking water, changing their bedding and even hosing off the back entrance to the house from all the duck poo they deposit as they wait by the door when they want in. The thing that bothers me is all the waste of the food at the bottom of their drinking water. There is always a nice goo at at the bottom. And cleaning it out leaves the goo on the ground and can get smelling. Am I feeding the wrong thing? Feeding them to much? Any suggestions? Also do you feed corn scratch for a treat? What percent protein? I am going to the feed store this week and am compiling a list. Thanks
