There's a gapeworm that attaches to the inside lining of the trachea (windpipe) but game birds are more likely to suffer from this parasite than are chickens. These worms can be present in such numbers that they may completely fill the airway resulting in extreme respiratory difficulty. Affected birds typically gasp for air and breathe with extended necks ("gape").

Loss of voice and lethargy can be seen with a number of respiratory infections - bacterial, viral, and fungal - and so, practically speaking, presumptively treating for a bacterial infection such as chicken coryza or avian mycoplasmosis with tylosin is reasonable. Tylan-50 is available in your local feed store and can be dosed at 20-30 mg/lb intramuscularly once daily for 5-7 days or you can give the injectable solution directly into Blackie's beak.

If you want to worm Blackie, fenbendazole (over the counter Panacur) is a good choice for all of the worms of chickens and is dosed at 10 mg/lb daily for 5 consecutive days. The usual fenbendazole suspension contains 100 mg/mL and is also found in your local feed store.

Please respond with further questions or concerns if you wish.
