I bought two 5 month old gold lace Wyandottes from a local farm on December 10. I have had them quarantined from the rest of my flock since then. A few days ago I noticed one of them has an eye that appeared to be slightly misshaped. Today it has really swollen up. I don't think it's Coryza there is no smell from her head. No nasal discharge. I hate giving antibiotics without really knowing what I'm treating. I'm hoping it's not something like MG, where even if she recovers she will remain a carrier. What about the other Wyandotte? Should I cull the one or both? Any advice appreciated. I have pics of both her eyes.Thanks
