Baytril (active ingredient: enrofloxacin) is an antibiotic and Baycox (active ingredient: Toltrazuril) is an anticoccidial parasiticide.
On that website is says: "Baycox, which is no longer readily available, was once the best cure for coccidia. Enrofloxin is now usually prescribed."
I think maybe she got baycox and baytril confused.

Name: Enrofloxacin (Commercial name: Baytril)
Description: Enrofloxacin is a synthetic chemotherapeutic agent from the quinolone class of drugs. It has antibacterial activity against a broad spectrum of Gram positive and Gram negative bacteria. it is rapidly absorbed and penetrates all body tissues well.
Usage: Enrofloxacin can be used with any bacterial infection showing susceptibility to the drug.
Adverse reactions: Enrofloxacin causes increased mortality in the egg when the hen is treated during egg formation. It will cause cartilage abnormalities in growing squabs, especially during the lst week to 10 days of age. This, however, is not always seen.
Dosage: 5 - 10 mg/bird divided daily for 7 - 14 days. 150 - 600 mg/gallon for 7 - 14 days.
Comments: Probably the best drug we have for the Gram negative infections of pigeons -- E. coli and paratyphoid infections. It is the only drug shown to prevent recurrence of shedding in most cases of salmonella infection at 6 mg/lb for 10 days. We assume that this means the carrier state has been eliminated in these birds. The liquid water-soluble form is available in Canada. Tablets are not water soluble.
And here are the COCCIDIOSTATS
Name: Amprolium (Commercial names: Corid, Amprol)
Description: Amprolium is a chemical that is very similar to thiamine (vitamin B1) in structure. It is coccidiostatic by substituting for thiamine during the coccidia life cycle.
Usage: As a coccidiostat.
Adverse reactions: None that are common.
Dosage: 1 teaspoon/gallon (20% powder) for 3 - 5 days. 6 - 12 mL/gallon (9% solution) for 3 - 5 days.
Comments: Amprolium is highly effective, can be mixed with other drugs, and doesn't seem to affect performance. It is considered by many to be the drug of choice for coccidiosis. Vitamins should not be used during treatment, but are recommended by many after treatment.
Name: Sulfamethazine (Commercial name: Sulmet)
Description: Sulfamethazine is a sulfa drug that is coccidiostatic.
Usage: As a coccidiostat.
Adverse reactions: May decrease vigor when used for the full course of treatment.
Dosage: 1 tablespoon/gallon for 3 - 5 days.
Comments: A popular coccidiostat but no better than amprolium in most cases. Birds typically become listless during treatment (full 5 days of treatment) and therefore it is not recommended for use during racing.
