You would have to ask the "Eye" experts. I was never convinced it made a difference, but at any rate perhaps the least important consideration IMHO. If you are pairing two Champions, I wouldn't care.i been hearing that you should breed a bird to a different eye color?
example: a pearl eye to a yellow eye , pearl eye to a green eye
and not a pearl eye to a pearl eye
have ya ever herd this? make's a different?
