Our 16 yr old Cockatiel has one nostril almost closed
Our 16 year old Cockatiel has one nostril that is almost closed. He has been to an Avian Vet several times about sneezing and clicky breathing, and was given antibiotics ( loxicom oral suspension and baytril 2.5% suspension - into drinking water )and the vet said he was reluctant to "poke around" his nostril.
He still has noisy breathing when he has flown around the room and then comes to you, sounds a little clicky, but otherwise seems his normal self.
We have just bought an Air Purifier and Avian full spectrum light bulb, and also some Kaytee bird greens and multi vitamins ( beaphar brand ), his diet consists of Cockatiel seed mix, Trill and mixed veg/fruit/greens - ie apple,orange,cucumber, salad leaves, peas,sweetcorn.
Could his nostril problem be a lack of vitamin A, And/or caused by dander ?
PS he also has to have his beak trimmed more frequently over the last few years as it grows irregular.
