eye colors

about a week or so ago one of my hens had a swollen and shut eye. so I put some neosporin on it. now it seems better although she does close it from time to time. but the eye looks different now. at first when she opened it back up it was all black and then some days later the iris looks orange...

I need to know more about eye color genetics. If anyone knows anything about eye color genetics post it here. I don't care if it is redundant information. This is the information I found after many internet searches. I can't find any more. Gene names would be great to add. Bk+dominant sex linked...
