I am new here and I have a question. I have a new Zebra Finch, who is interesting. (And yes he is on quarantine away from my flock) I know males have orange cheeks. This Zebra Finch has ONLY ONE ORANGE CHEEK. Is this mutation rare? The other cheek is white and only has a partial tear line... it's more like a dot. He also had a nasty eye infection when I got him that is improving quickly with the help of Terramycin. Has anyone seen this before? If so did the bird have any behavioral issues? My little guy seemed defensive toward the other birds at the store. (I wasn't there to buy a bird but saw him and felt he needed help) I am worried about how to integrate him after he is healthy.
