Never force water or liquid down the beak, which causes aspiration pneumonia into the open tracheal glottis.<\/li>\n<li><strong>Sanitize flock equipment and premises:<\/strong> Thoroughly clean and disinfect coop waterers, feeders, and roosting perches with avian-safe disinfectant. Remove damp bedding litter immediately.<\/li>\n<li><strong>Collect baseline diagnostic data:<\/strong> Note the consistency of droppings, respiration rate, crop fullness, and comb coloration over 24 hours. Record changes in body weight daily to inform veterinary consultation.<\/li>\n<li><strong>Schedule avian veterinary examination:<\/strong> If the bird displays progressive lethargy, respiratory rales, neurological signs, or severe dehydration, contact a licensed poultry veterinarian for prescription diagnostics.<\/li>\n<\/ol>\n<h2>What veterinary tests confirm urolithiasis in poultry?<\/h2>\n<p>Accurate identification requires professional veterinary diagnostics rather than keeper guesswork.
