Chickens are so hard to diagnose for causes... they are smaller animals & don't have a dog/cat physiology so symptoms are not easy to pinpoint to a cause. Sometimes it can be an allergy, diet deficiency, sensitive chronic condition, latent internal condition, etc. So, sometimes all we can do is treat a symptom without ever knowing why. Sometimes tests can reveal problems... but at best it's a guessing game for us w/o a vet's assistance.Terramycin antibiotic ointment in the eyes, once a day for seven days. This and including meloxicam for swelling was the vet plan last July when she had a bad flare up and one eyelid was swelling too, the vet thought that and the flare up was due to dust irritation and then particulate matter caught in there. No swelling this time, and I’m not sure of the cause for the flare-up, it’s not real dusty in their run or coop.
I did just one apparently pretty bubbly eye the first day, then her other eye was really foamy the next day, so I’m doing both eyes.
Sometimes even if we know the problem we still can't do anything if it's arthritis, tumor, cancer or reproductive issues
~ Like Ponypoor says... all we can do sometimes is pain mgmt.
