If possible, consult your veterinarian. Do not attempt if you cannot safely and gently carry and restrain your bird. Do not attempt if bird's crop is full of water as aspiration can occur from handling. Do not attempt until you know the difference between the oesophagus and the trachea. Do not do if your bird is molting. Choose your mg/kg of fenbendazole, liquid or paste. I do 50mg/kg From:http://www.hopkinslivestock.com/oral_dosing_article.htm The hole at the back of the tongue is the trachea - Nothing should ever go in there! Get your supplies ready Catch and weigh your bird. Calculate dose and prepare one or more syringes. Please note that this method will work for those who use a 1cc/ml syringe. Anything larger is too big and IMNSHO, not safe! Please note that I was the one holding the bird and taking the pictures, please use both hands! Hold bird - I like to sit with my thighs parallel to the ground, feet firmly on ground and the bird in my lap. I hold it gently, but firmly and grab the head. Open mouth and wait for bird to relax. Insert syringe - I like to insert from left to right, across the tongue, behind the trachea, into the oesophagus. Again, wait for the bird to relax. Give wormer Repeat in ten days.
