My beardie also seemed to turn his nose up at his greens. I had been giving him turnip greens since we got him this past summer, then all of sudden he was finicky. So I switched to Romaine but in reading some of the other posts, Romaine may not be an ideal choice. He did begin to eat his greens again. I also noticed that once my greens reached a certain ripeness, they were not welcome. Just make sure the greens are fresh...although the greens I offered were about a week and a half old, he was not interested. Maybe this will help.
