I haven't heard back from the company yet. Someone on another forum who works at a Petco near to this one has contacted the regional animal coordinator about this. And if nothing is improved in a few days to a week I will be getting in touch with the SPCA.

I did take some pictures of his vent, the back of his head where the other budgie was biting him, his tail, and his keel, so if they want to argue that he was in good shape I have proof that shows otherwise.
