Here is something from Kathy's URL on Baytril:

Just a disclaimer about antibiotic use, especially if you are not consulting with a vet. There are good reasons for the regulation of antibiotics (Though I definitely don't agree with the prices!). One major reason is that giving antibiotics without knowing exactly what is going on with the animal can contribute to antibiotic resistance of the organisms associated with that animal. The use of antibiotics in farm animals is a major problem in human medicine because many pathogens that affect people are becoming resistant. For a long time, antibiotic use in slaughtered animals went unchecked. Now there are strict regulations and withdrawal times for food animals, and veterinarians work hard to regulate the use of antibiotics so that they are used only in animals that absolutely need them.
As far as I know, baytril is not labeled for use in poultry, so I would not use this in birds that will be food or that lay eggs for human consumption. People who have given baytril to chickens in the past generally keep their eggs from consumption (Some people do this for the life of the bird). Another related issue is that if these antibiotics are used and you have no plans to eat the bird, there is no guarantee that if the bird is sold that the next person will do the same, even if they are told the bird has been treated with antibiotics.
Another issue is that antibiotics can be specific for certain pathogens (I see some listed above) so if a person gives one type of antibiotic without knowing the cause of disease, it may not do anything at all.
If you are advised to give this under direction of a vet, then by all means buy it from a cheaper source such as the ones listed!
