I had a silkie shipped to me from NC and it had everything your describing, It would fling a foul yellow discharge from it's nostrils, and her eyes would bubble and she had to breath from her mouth. We took her to a good avian vet and was diagnosed with Chronic respiratory disease (CRD). I'm not saying this is what your bird has. My bird had to go on Baytril shots and it cleared up immediately! They were $15 a shot when I had to get them. This is her with the discharge crusted over.
