The pigeon is not quite a year old, usually heathy and cage bound. His cage is dirty (in need of cleaning). He shares his cage with several other birds. Symptoms are primarily dizziness. His pupils seem dialated and he can't focus very well. Sudden movements will make him fly. Should I just treat this with antibiotics? If its head trauma there isn't much I can do, but could this be coccidiosis. I have been feeding him fresh greens. Suggestions welcome. Thanks.
