Baytril is what I would use in mine, but it's been banned for use in poultry and my vet made me promise never to eat anything that I gave Baytril to. Read this:
Dangers for Eggs & Meat
One study found that eggs and meat cleared of Baytril just
5 days after chickens stopped receiving the medicine, but other studies haven't always concurred, and no official withdrawal time is listed in the U.S.
There are other
serious concerns that have caused
Baytril to be banned in the US from
use in poultry used for eggs or meat.
- When exposed to Baytril, Campylobacter bacteria may become resistant to Cipro, a primary medicine used for treating people infected with food poisoning or urinary tract infections. If this bacteria is in a chicken and is not killed during cooking of eggs or meat from a chicken that EVER took Baytril, a person eating the food might not be able to be treated successfully with Cipro.
Where to buy Baytril
Poultry: Pet supply and vet medicine stores & online retailers sell Baytril. However, it is illegal in the US to sell Baytril for "egg or meat-producing birds", because of possible risks to people, & most online sellers would require a vet's prescription to be able to sell you Baytril labeled for use in poultry. Some vets will sell Baytril directly to you if they determine it would be advisable for your bird.
Other birds: Prescriptions are not required for small pet birds. A search online for "Baytril birds" will list some retailers of supplies for small pet birds, and these sellers may not need prescriptions.
