I would just be up front with the buyers and tell them you have been treating some birds and advise they isolate them and keep an eye out. Which a person who already has a flock should do anyway, but not everybody does. I would not sell them if you see they are infested until you clear them up. If you are selling the males for meat you should not use anything that leaves a residual in the tissue. We really do not know any withdrawal time for that stuff since it is not approved for poultry and Americans don't eat their dogs![]()
