I had a Roo with a swollen eye and when I went to grab him from to coop to be quarantined I noticed a hen also had a slightly swollen eye. I separated them and since then the roo's eye has returned to normal but the hen's has been getting worse. There are no strong smells, she is still eating and drinking, she has no nasal discharge and she seems in good spirits. Her other eye is not affected at all. If anyone has any ideas or suggestions they would be greatly appreciated!
