I'm not a vet, but if I were and someone said "This bird is sick." I hope the first question I'd ask is "Why do you think so?" Not to doubt the person but to figure out what the presenting symptoms were.
It is not abstract general someone. It is very concretely more experience professional and teacher whose judgement you trust more then your own. And no, if you dont go much out of way to be approachable or have reason to be afraid of him, no matter how small, they will not ask more. Because most interns know they are beginners and don't know yet.
