While i was setting eggs i talked to two other owners that are npip. Both have been told use of any banned drug will get npip pulled period. Was also informed they dint have to have proof you have used it at all. Having a banned drug on premises is enough to get your npip pulled. I'm not trying to be an ahole but if i was you id delete anything off the forum having to do with using baytril at all. I know for a fact fish and game agent patrol this forum. If they do it you know feds do too. Their inspector checks their drug supplies each time he is there.
I think that prescribing veterinarians might be at risk, too. I've been told that some will not give/prescribe Baytril to anyone with poultry.
