Slighty swollen eye...what to give chick and how much

[Carchick]

My male chick will be 6 weeks old on Saturday. His right eye is slightly swollen, not sure how, he's in a big box in our dining room until he's ready to move out to the coop, there is one other chick in there with him. It's been like this for awhile, didn't think much of it, just thought it would get better. He doesn't really use that eye, he always uses the other one to look at us. Yesterday I put warm water on a washcloth and put some saline solution on a cotton ball. I would think I should use eye drops or some sort of antibiotic. He's not sneezing, nothing coming out of eye, seems to be lethargic at times, well at least compared to his sister. What eye drops should I get (from feedstore), what dosage, if antibiotics, what kind and dosage. If I put it in water, is it ok for the other chick to drink it too?

Here's a picture:

I would not use medication unless other symptoms appeared. i have never seen eye drops at the feed store so I wouldn't know what to reccomend if you decide to do that

I have been giving her (thought she was a he at first!) 2 drops of polyvisol vitamins.....she loves it. Her eye is still slightly swollen but I don't believe as much as it looks in this picture anymore. What concerns me though, is that the other eye appeared the same way now, only slightly, and in this pic, the pupils look dialated. She eats plenty, drinks just fine, seems slightly lethargic at times, and I just introduced yogurt to help with that. Other than that no other symptoms. So far they're not wild about it, well it was the first day so I'll keeping giving it to them. What do you think about the dialated pupils? Also the inside corner of her eye is light pink. I've read in other posts about blindness, but since she's had it for awhile, I don't think that's going to happen, hopefully.
