Yes, ask your vet for an antibiotic. They usually keep some on hand. If they can give you a week's doses, you can get her started right away. Then order the amoxicillin tonight, and when it comes, you can switch her over to that, unless the vet can give you the full round of treatment.
Get the fish mox ordered and on the way. It's not expensive. It will keep for years, and you'll have it on hand when another chicken needs it. I keep an assortment of antibiotics on hand.
If you have friends or relatives you could ask to go look in their bathrooms for any leftover prescription antibiotics, you can use those on chickens. I have several of those that people have given me for my chickens.
