I have nine Campbell hens i want to sell, but at this point cannot. if i get chicks in the spring, could i add them to the ducks, should the ducks not sell. I am concerned about the ducks sloppiness with water and poop causing sickness in the chooks. also, ducks lay anywhere--not in boxes off the ground. so this can promote egg eating among the chooks. if i could just sell those ducks!!!!!!!!!!!
