I noticed one of our buff orpington hens this morning has her eyes swollen and running and I believe she has some nasal discharge. Is this a cold and where do I start with treatment? I do have a bottle of Vet RX and just read the instructions and have the bottle in warm water warming it up. Would this be a good start for her treatment. I cleaned out one of our brooders and put fresh shavings and water and food in it so I can isolate her and keep her warm. How do I proceed with treatment this is my first sick chicken have had birds for almost a year now. Any suggestions would be greatly appreciated.
