hello! three days ago we got a baby cockatiel (less than a month old) our concerns are that the baby has difficulty breathing and the symptoms are : tail bobbing, heavy breathing, there is something like a balloon increasing and decreasing which is located on his right side of the neck when he is breathing, he is also has something like ''wet'' sneezing, has wheezing sounds when he breaths. we are fully aware that he can get aspiration when giving him baby formula but we are very gentle when we are feeding him. Please help us, we don't have expert for birds in our country, Bulgaria. I''ve purchased doxycycline just in case he needs, but we are not sure how much to give him since he is a baby. Also his poop is normal, has its white spot in it, not watery, brownish (which i saw its normal for baby parrot who are given formulas) Thank in advance!
