I was told by a vet. to use Wazine to treat my flock for round worms. (We had lost 1/2 of the flock before an autopsies diagnosed round worms.) The vet told us to use it once a week for three weeks, with a 14 day withdrawal period for the eggs at the end of the treatment. The bottle of Wazine clearly states, "Do not use in hens producing eggs for human consumption." Does anyone know which information is correct? Thanks.
