Welcome to Justanswer! I am Dr. Altman and happy to assist you both today!
I am so sorry to hear Brooks has this cough. You can try a piece of bread to see if there is any residual pieces of the feather in the esophagus that he is trying to cough up. This will help protect the piece and move it through hopefully without doing any harm to the intestinal tract. Monitor for any pieces out the other end in 24-48 hours.
As for the cough if unrelated to the feather but provide relief, there are some home remedies that can help reduce the cough
1.) The steam of the shower when the cough is severe or constant
2.) A little honey three times daily can help soothe the lungs
3.) If you have a humidifier or nebulizer that would also be wonderful to use in this situation
Unfortunately I prefer to avoid cough suppressants because when suppressing a cough if there is phlegm or buildup and lead to bronchitis or even pneumonia if the material is not coughed up so this is not something I tend to administer.
I hope this information makes sense! if the cough becomes productive I would advise a veterinary exam to ensure antibiotics are not warranted. In addition if there is development of lethargy or a reduced appetite then it would be best to have a veterinary exam.
Please let me know if I can be of any further assistance to you both!
