I hope this helps, even though its long- I do hope that your beardie is doing okay
Blue Poop
That? This may or may not help at all, but things like blueberries or squash may tint the color of your bearded dragon’s poop. As long as your lizard’s food seems to be the culprit, this is no cause for concern. Just avoid giving him the presumed offending item for a day or two and ensure that his droppings return to normal color. If it were something else, I'd take him to the vet.
