Greetings Angie1701
I had something similar happen to one of my roosters. It's not fun having anyone messing with your eye. Eggcessive gave good treatment advice to follow. Also, if you have a broad spectrum antibiotic you can give him for 5-7 days that would be good too.
His eye can heal if you treat with the Terramycin consistently. Will it be normal again? You will have to wait and see, in about a week or so. What you have to watch out for, is secondary infection.
I focused on my rooster's eye injury and never thought he was suffering. After a week, he suddenly collapsed while I was working in his pen. I quickly took him to my Vet, and he was diagnosed with a serious respiratory infection. His body temp had fallen very low. I had to treat with antibiotic injections and bring him in the house for 2 days, till he was back on his feet.
I recommend that you put your rooster in a hospital crate for a few days, with time out for exercise daily. Then, you can administer medication and observe his progress. If you have multiple roosters, then you will have to keep them together of course. Otherwise he will not be able to return to the coop.
Provide supportive care.
Feed him well: diced
cooked meat protein or cooked eggs, diced fruit, diced black or red grapes, fresh greens, cooked grains like: brown rice, wheat berries, oat groats, pearl barley, also some toast with butter is good. Always offer him feed daily, too.
Clean fresh water daily. I like to add some echinacea tea or aloe vera, to boost the immune system.
Keep him out of cold and windy conditions till he is fully recovered.
These are my thoughts...I hope they are helpful.
