water bowl

My cockatiel will pretty consistently (a couple times a week) get water up his nose and then have this squeaky honking noise he does for about 10 minutes afterwards (can’t attach a video :( ). His nares always look clear and healthy, and he never has any nasal discharge that isn’t just the water...

Hi, I recently read that a few drops of apple cider vinegar in my cockatiel's water bowl and in her chop can help reduce bacterial growth and can provide her nutrients. Is this true and safe? Any comments on how much I shld give my 8month cockatiel if it's safe and healthy to do so? Thanks in...
