Hi I am new here, I am looking after my parents parrot for a quite a while so I am new to the whole parrot thing, he is a blue crowned conure called Charlie and is 25 years old. I had to take him to the vet recently and he was given lots of tests and xrays, they told me he had a repository disease and slightly low protein. I was also told he would need a nebuliser, the vet recommended a childs one. I wondered if anyone here could tell me how I use the nebuliser on Charlie as I would really appreciate the help

Also any advice and help on looking after a Conure would be greatly appreciated please as I really want the best for him.
Also my parents never really handled him or had him out of the cage and I know that they should be so I wondered if I would still be able to train him to come out of the cage and be handled even though I know he is quite old. His wings aren't clipped and he does bite a bit but I just want to make his stay as comfortable as possible with us.
