Apparatus and methods for delivering a composition to a bird. A selected dosage of the composition may be delivered directly to one or both nostrils of the bird. The deliveries are performed through one or two fluid passages that are preferably in direct fluid communication with the birds' nostrils. Delivery of the composition may limited to only one nostril or both nostrils of each bird. The nostril or nostrils to which the selected dosages are delivered may be isolated from fluid communication with ambient atmosphere during the delivery process. The isolation may be provided by a conformable seal. The beak of the bird may be restrained in a closed position during delivery of the composition.
