I myself have no problems tossing away out-of-date antibiotics. Just means no one needed it and that makes me happy.
2 Antibiotics I always have here just in case.
Fish-Mox: Yes they are made for aquariums, but it is the same thing and CHEAPER. I get 100 capsules bottles at 250 mg of Amoxicillin each for $14.18 on ebay from
http://stores.ebay.com/countrysidepetsupply. Capsules last alot longer then injectable and powder. For dosage all you have to do is wet a capsule and pop it down the birds throat. The 'wetting' is so that is doesn't stick to the inside of the mouth or tongue.
Amoxicillin is your go it antibiotic for infection from injury, sepsis, crop infections, sour crop, gut infections, egg binding, and even some respiratory issues. I have given it to both bantams and standards with great success over the years. Treatment for most things is 1 a day for 5-7 days.
Tylan 50 and syringes(bulk box of 1CC slip lock syringes and another of 25 guage needles): All around treatment for alot of respiratory issues. The slip lock syringes have a longer tip that the needle slides on. These come in handy for use as a dropper/force feeder as well. I also have some 6CC with the slip lock that I use for worming with Ivomec.

Edited to add: I have also used Fish-Mox to treat myself. LOL
