I have a B/G Macaw who is about 5 years old. Great temperament, appetite, and very active. The question I have is in the last day or so he's develop redness or flushing on the right side of his face? He kept blinking and closing his eye for awhile but that has stopped. It seems to be lessoning but I was just wondering if anyone had any ideals? Could a full spectrum light have created this condition? That's the only thing I’ve changed.
