Oral Antibiotics for Injuries?

[Florida Backyard Chickens]

One of our favorite hens went missing for a few days and just wandered back up with a pretty severe injury under wing that already smells pretty rotten. We sprayed the wound down good with vetericyn but I’m wondering if there’s an oral antibiotic at feed stores that may be helpful?

You can give her Amoxicillin for fish. Dosage is one 250mg capsule twice a day for 10 days. Here's where you can purchase it.
