I recently purchased 6 hens from a local farm. 2 R.I.R's and 4 Red Stars. After a few days I noticed that one of the Red Stars had her eye closed often. Otherwise she appeared normal. Eating, drinking and scratching like the rest. She would just sleep more often then the rest. I assumed this was from the stress of re-homing. Today (about a week later) one of the Rhode Island Reds had two swollen eyes and they were watery. This particular hen was the most dominant hen so far and today she was off in the corner. She doesn't appear lethargic yet and she drank water when i put her in front of it. I separated her and treated with VetRX. The other hen never progressed to this level. She just had one eye closed every once in a while. Here are a couple pictures. Any input would be great!
