I think Vet Rx is used to treat eye worms. It's an all natural product, I think. Here is the blurb from their website:
VETRX POULTRY Effective relief from respiratory diseases, CRD, roup, scaley leg mites, favus, eye worm - for all poultry - chickens, turkeys and game birds
******Edited to say I have never used it
in any chickens' eyes and have never had this problem. I am only saying that the
instructions on the package of Vet Rx say it can be used for eye worm and how to do it. Someone hinted elsewhere that it was nuts to do so and that I should not have said anything about using it, but I was not
endorsing it, just offering the only thing I've ever seen as a product to extract eye worms. As anyone should, I follow directions on the medications for chickens since I don't have a vet degree.
This is the way the label says to use it:
"Eye Worm"
This affliction is most harmful to game birds, which must have good, clear vision at all times. The tiny worm works its way under the third eyelid and causes a pus pocket to form. The bird will blink excessively and rub its eye at base of wing feather.
To treat, hold bird under your arm so you have both hands free. Open bird's mouth while turning its head to side and tilting down so you can see the cleft in the roof of the mouth. Dip a small cotton swab into warm VETRX. Press swab right into cleft. Do this slowly. Watch for VetRx to come from each side of bird's beak and pus coming from corner of each eye. Remove pus and rest bird for awhile. You may have to repeat treatment two or three times before you see results.
