I put the Wazine 17 in the water like the instructions said. 2 tablespoons to a gal. They may have drank a pint of it. The nest morning there were pinkish round worms about a 1 and a half long on the poop. I went about the yard picking up what I could find and still at times found a worm in the poop. This morning I replaced that water with fresh water with ACV in it. Now I'm told to do the same thing over again in 14 days. Then after that when do I worm with the Valbazen? Is there a waiting period after the Wazine dose or should I do it before the 14 day waiting period. I did notice not all the birds had worms. The BO's seemed to be the worst. I know where each one roost so I've learned what pile belongs to whom. I know my birds buy there poop. Now bout that?
