A system for treating wild birds includes an enclosure formed of a mesh material large enough to accommodate a plurality of wild coveying birds targeted for treatment. A call bird box is positioned within the enclosure. A call bird of the same species as the targeted birds is housed in the call box and makes calls for attracting the targeted birds. At least one ground level entrance is provided, sized and located to permit the entry of targeted birds into the enclosure while excluding non-targeted animals. A feeder containing medicated feed is provided within the enclosure for feeding the targeted birds entering the enclosure in order to treat the targeted wild coveying birds for parasites or disease. A cover is provided for protecting the medicated feed in the feeder from the environment. Methods for installing such a treatment system and treating wild birds using a treatment system are disclosed.
