Question: how long do antibiotics take to work in chickens?
Answer: We recommend two prescription antibiotics: a) BAYTRIL. Give one 22.7 mg (milligram) tablet per five pounds of bodyweight twice a day, morning and evening, for 10 to 14 days. DO NOT STOP GIVING AN ANTIBIOTIC AFTER A FEW DAYS WHEN SYMPTOMS SEEM TO DISAPPEAR.
