This is a blue slate then a little more than a year old. Her eyes have been looking really swollen and rhuemy. I've given her Tylan IM and vit b. I've also rubbed her head with VetRX, that's what has caused the little black spots, it's dirt adhering to the oil. Her lungs sound clear, and she has no nasal discharge. She's not looking right, kind of has her feathers poofed out, and she's not as active as usual. any ideas on what may be wrong with my girl?
