Bennie is a pearl pied. He'll be 6 this October. I was lying back in my recliner the other day with Bennie sitting on my chest. He walks back and forth and chirps and talks to me. I noticed his eyes seem to have a lighter iris that they did. I thought his eyes were all black, like tiny beads or buttons. But now it looks like he has a brown iris. It was just slightly lighter; it may have been that I just never noticed before. Do their irises lighten as they get older?
