HELP PLEASE!! 3 month old injury or defect? Possible blindness!

[mychookschick]

So, yesterday I went and picked up 11 chicks/pullets (not sure what to technically call them), 4 of them are 5 months old and them other 7 are 3 months old. I got them home and it was after dark so I didn't cuddle them or anything just put them to bed. This morning I noticed that the smallest 3 month old as a sot of compressed eye socket... looking thing.... on one side. Her (or his) eye is all squinty! She seems to be having trouble finding the food and water... I assume that is why she is so small. She isn't being picked on at all but she can't run without tripping over something or someone...

I feel horrible! I hand-fed her and she ate a whole handfull! She also readily drank some water.

When I waved my hand in front of her good eye she was looking around trying to figure out what it was. Then, when I waved my hand by her bad eye she did reletively nothing and then turned her head to see what was going on on the other side of the coop....

I am very worried about her and would appreciate suggestions and feedback if you have had chickens with eye issues.... for example: Did they survive? Did they require additional care? Did they still produce the way they should? and in general anything else you think I should know before embarking on this endeavor....

Many thanks to all helpful and uplifting replies!
