For those that don't know, many livestock medications will no longer be sold over the counter by January 1, 2017. According to the new laws, these medications will only be available by veterinarian prescription. We highly recommend stocking up on these before they are no longer easily available. Most have a 2 year shelf life. The following are commonly used for poultry. They may still be available at your local farm supply store, or you can order them here:
Tylan 50 IV
Oxytetracycline (Duramycin) powder
Terramycin ophthalmic ointment
